Suicide is the act of intentionally causing one’s own death. Mental disorders, including depression, bipolar disorder, schizophrenia, personality disorders, anxiety disorders, and substance abuse—including alcoholism and the use of benzodiazepines—are risk factors. Some suicides are impulsive acts due to stress, such as from financial difficulties, troubles with relationships, or bullying. Those who have previously attempted suicide are at a higher risk for future attempts. Effective suicide prevention efforts include limiting access to methods of suicide—such as firearms, drugs, and poisons; treating mental disorders and substance misuse; proper media reporting of suicide; and improving economic conditions. Even though crisis hotlines are common, there is little evidence for their effectiveness.
The most commonly used method of suicide varies between countries, and is partly related to the availability of effective means. Common methods of suicide include hanging, pesticide poisoning, and firearms. Suicides resulted in 828,000 global deaths in 2015, an increase from 712,000 deaths in 1990. This makes suicide the 10th leading cause of death worldwide.
Approximately 0.5% of people die by suicide. In a given year this is roughly 12 per 100,000 people. Rates of completed suicides are generally higher among men than among women, ranging from 1.5 times as much in the developing world to 3.5 times in the developed world. Suicide is generally most common among those over the age of 70; however, in certain countries, those aged between 15 and 30 are at the highest risk. Europe had the highest rates of suicide by region in 2015. There are an estimated 10 to 20 million non-fatal attempted suicides every year. Non-fatal suicide attempts may lead to injury and long-term disabilities. In the Western world, attempts are more common among young people and among females.
Views on suicide have been influenced by broad existential themes such as religion, honor, and the meaning of life. The Abrahamic religions traditionally consider suicide as an offense towards God, due to the belief in the sanctity of life. During the samurai era in Japan, a form of suicide known as seppuku (harakiri) was respected as a means of making up for failure or as a form of protest. Sati, a practice outlawed by the British Raj, expected the Indian widow to kill herself on her husband’s funeral fire, either willingly or under pressure from her family and society. Suicide and attempted suicide, while previously illegal, are no longer so in most Western countries. It remains a criminal offense in many countries. In the 20th and 21st centuries, suicide has been used on rare occasions as a form of protest, and kamikaze and suicide bombings have been used as a military or terrorist tactic.
Suicide, from Latin suicidium, is “the act of taking one’s own life”. Attempted suicide or non-fatal suicidal behavior is self-injury with at least some desire to end one’s life that does not result in death.Assisted suicide is when one individual helps another bring about their own death indirectly via providing either advice or the means to the end. This is in contrast to euthanasia, where another person takes a more active role in bringing about a person’s death. Suicidal ideation is thoughts of ending one’s life but not taking any active efforts to do so. It may or may not involve exact planning or intent. In a murder-suicide (or homicide-suicide), the individual aims at taking the life of others at the same time. A special case of this is extended suicide, where the murder is motivated by seeing the murdered persons as an extension of their self. Suicide in which the reason is that the person feels that they are not part of society is known as egoistic suicide.
The normal verb in scholarly research and journalism for the act of suicide is commit. Some advocacy groups recommend saying completed suicide, took his/her own life, died by suicide, or killed him/herself instead of committed suicide. Recommended journalistic practice is to use “died by suicide”, “completed”, or “killed him/herself”. The Associated Press Stylebook recommends avoiding “committed suicide” except in direct quotes from authorities. Opponents of commit argue that it implies that suicide is criminal, sinful, or morally wrong.
Socio-economic problems such as unemployment, poverty, homelessness, and discrimination may trigger suicidal thoughts. Suicide might be rarer in societies with high social cohesion and moral objections against suicide. About 15–40% of people leave a suicide note. War veterans have a higher risk of suicide due in part to higher rates of mental illness such as post traumatic stress disorder and physical health problems related to war. Genetics appears to account for between 38% and 55% of suicidal behaviors. Suicides may also occur as a local cluster of cases.
Others estimate that about half of people who complete suicide could be diagnosed with a personality disorder with borderline personality disorder being the most common. About 5% of people with schizophrenia die of suicide. Eating disorders are another high risk condition.
Among approximately 80% of completed suicides, the individual has seen a physician within the year before their death, including 45% within the prior month.Approximately 25–40% of those who completed suicide had contact with mental health services in the prior year. Antidepressants of the SSRI type appear to increase the frequency of suicide among children but do not change the risk among adults. An unwillingness to get help for mental health problems also increases the risk.
Previous attempts and self harm
A previous history of suicide attempts is the most accurate predictor of completed suicide. Approximately 20% of suicides have had a previous attempt, and of those who have attempted suicide, 1% complete suicide within a year and more than 5% die by suicide within 10 years. Acts of self-harm are not usually suicide attempts and most who self-harm are not at high risk of suicide. Some who self-harm, however, do still end their life by suicide, and risk for self-harm and suicide may overlap.
A number of psychological factors increase the risk of suicide including: hopelessness, loss of pleasure in life, depression, anxiousness, agitation, rigid thinking, rumination, thought suppression, and poor coping skills. A poor ability to solve problems, the loss of abilities one used to have, and poor impulse control also play a role. In older adults the perception of being a burden to others is important. Those who have never married are also at greater risk. Recent life stresses such as a loss of a family member or friend or the loss of a job might be a contributing factor.
Certain personality factors, especially high levels of neuroticity and introvertedness, have been associated with suicide. This might lead to people who are isolated and sensitive to distress to be more likely to attempt suicide. On the other hand, optimism has been shown to have a protective effect. Other psychological risk factors include having few reasons for living and feeling trapped in a stressful situation. Changes to the stress response system in the brain might be altered during suicidal states. Specifically, changes in the polyamine system and hypothalamic–pituitary–adrenal axis.
Social isolation and the lack of social support has been associated with an increased risk of suicide. Poverty is also a factor, with heightened relative poverty compared to those around a person increasing suicide risk. Over 200,000 farmers in India have died by suicide since 1997, partly due to issues of debt. In China suicide is three times as likely in rural regions as urban ones, partly, it is believed, due to financial difficulties in this area of the country.
The time of year may also affect suicide rates. There appears to be a decrease around Christmas, but an increase in rates during spring and summer, which might be related to exposure to sunshine.Another study found that the risk may be greater for males on their birthday.
Being religious may reduce one’s risk of suicide while beliefs that suicide is noble may increase it. This has been attributed to the negative stance many religions take against suicide and to the greater connectedness religion may give. Muslims, among religious people, appear to have a lower rate of suicide; however the data supporting this is not strong. There does not appear to be a difference in rates of attempted suicide rates. Young women in the Middle East may have higher rates.
Most people are under the influence of sedative-hypnotic drugs (such as alcohol or benzodiazepines) when they die by suicide with alcoholism present in between 15% and 61% of cases. Use of prescribed benzodiazepines is associated with an increased rate of attempted and completed suicide. The prosuicidal effects of benzodiazepines are suspected to be due to a psychiatric disturbance caused by side effects or withdrawal symptoms. Countries that have higher rates of alcohol use and a greater density of bars generally also have higher rates of suicide. About 2.2–3.4% of those who have been treated for alcoholism at some point in their life die by suicide. Alcoholics who attempt suicide are usually male, older, and have tried to take their own lives in the past. Between 3 and 35% of deaths among those who use heroin are due to suicide (approximately fourteen fold greater than those who do not use). In adolescents who misuse alcohol, neurological and psychological dysfunctions may contribute to the increased risk of suicide.
The misuse of cocaine and methamphetamine has a high correlation with suicide. In those who use cocaine the risk is greatest during the withdrawal phase. Those who used inhalants are also at significant risk with around 20% attempting suicide at some point and more than 65% considering it.Smoking cigarettes is associated with risk of suicide. There is little evidence as to why this association exists; however, it has been hypothesized that those who are predisposed to smoking are also predisposed to suicide, that smoking causes health problems which subsequently make people want to end their life, and that smoking affects brain chemistry causing a propensity for suicide. Cannabis, however, does not appear to independently increase the risk.
There is an association between suicidality and physical health problems such as chronic pain, traumatic brain injury, cancer, kidney failure (requiring hemodialysis), HIV, and systemic lupus erythematosus. The diagnosis of cancer approximately doubles the subsequent frequency of suicide. The prevalence of increased suicidality persisted after adjusting for depressive illness and alcohol abuse. Among people with more than one medical condition the frequency was particularly high. In Japan, health problems are listed as the primary justification for suicide.
Sleep disturbances such as insomnia and sleep apnea are risk factors for depression and suicide. In some instances the sleep disturbances may be a risk factor independent of depression. A number of other medical conditions may present with symptoms similar to mood disorders, including hypothyroidism, Alzheimer’s, brain tumors, systemic lupus erythematosus, and adverse effects from a number of medications (such as beta blockers and steroids).
This trigger of suicide contagion or copycat suicide is known as the ‘Werther effect’, named after the protagonist in Goethe’s The Sorrows of Young Werther who killed himself and then was emulated by many admirers of the book. This risk is greater in adolescents who may romanticize death.It appears that while news media has a significant effect; that of the entertainment media is equivocal. It is unclear if searching for information about suicide on the Internet relates to the risk of suicide. The opposite of the Werther effect is the proposed ‘Papageno effect’, in which coverage of effective coping mechanisms may have a protective effect. The term is based upon a character in Mozart’s opera The Magic Flute—fearing the loss of a loved one, he had planned to kill himself until his friends helped him out. When media follows recommended reporting guidelines the risk of suicides can be decreased. Getting buy-in from industry, however, can be difficult, especially in the long term.
Trauma is a risk factor for suicidality in both children and adults. Some may take their own lives to escape bullying or prejudice. A history of childhood sexual abuse and time spent in foster care are also risk factors. Sexual abuse is believed to contribute to approximately 20% of the overall risk. Significant adversity early in life has a negative effect on problem-solving skills and memory, both of which are implicated in suicidality.
Problem gambling is associated with increased suicidal ideation and attempts compared to the general population. Between 12 and 24% pathological gamblers attempt suicide. The rate of suicide among their spouses is three times greater than that of the general population. Other factors that increase the risk in problem gamblers include mental illness, alcohol and drug misuse.
Genetics might influence rates of completed suicides. A family history of suicide, especially in the mother, affects children more than adolescents or adults. Adoption studies have shown that this is the case for biological relatives, but not adopted relatives. This makes familial risk factors unlikely to be due to imitation. Once mental disorders are accounted for, the estimated heritability rate is 36% for suicidal ideation and 17% for suicide attempts. An evolutionary explanation for suicide is that it may improve inclusive fitness. This may occur if the person dying by suicide cannot have more children and takes resources away from relatives by staying alive. An objection is that deaths by healthy adolescents likely does not increase inclusive fitness. Adaptation to a very different ancestral environment may be maladaptive in the current one.
Infection by the parasite Toxoplasma Gondii has been linked with suicide risk. One explanation states that this is caused by altered neurotransmitter activity due to the immunological response.
Euthanasia and assisted suicide are accepted practices in a number of countries among those who have a poor quality of life without the possibility of getting better. They are supported by the legal arguments for a right to die.
The act of taking one’s life for the benefit of others is known as altruistic suicide. An example of this is an elder ending his or her life to leave greater amounts of food for the younger people in the community. Suicide in some Inuit cultures has been seen as an act of respect, courage, or wisdom.
A suicide attack is a political or religious action where an attacker carries out violence against others which they understand will result in their own death. Some suicide bombers are motivated by a desire to obtain martyrdoms or are religiously motivated. Kamikaze missions were carried out as a duty to a higher cause or moral obligation. Murder–suicide is an act of homicide followed within a week by suicide of the person who carried out the act.
Mass suicides are often performed under social pressure where members give up autonomy to a leader. Mass suicides can take place with as few as two people, often referred to as a suicide pact. In extenuating situations where continuing to live would be intolerable, some people use suicide as a means of escape. Some inmates in Nazi concentration camps are known to have killed themselves by deliberately touching the electrified fences.
The leading method of suicide varies among countries. The leading methods in different regions include hanging, pesticide poisoning, and firearms.These differences are believed to be in part due to availability of the different methods. A review of 56 countries found that hanging was the most common method in most of the countries, accounting for 53% of the male suicides and 39% of the female suicides.
Worldwide, 30% of suicides are estimated to occur from pesticide poisoning, most of which occur in the developing world. The use of this method varies markedly from 4% in Europe to more than 50% in the Pacific region. It is also common in Latin America due to easy access within the farming populations. In many countries, drug overdoses account for approximately 60% of suicides among women and 30% among men. Many are unplanned and occur during an acute period of ambivalence. The death rate varies by method: firearms 80–90%, drowning 65–80%, hanging 60–85%, car exhaust 40–60%, jumping 35–60%, charcoal burning 40–50%, pesticides 60–75%, and medication overdose 1.5–4.0%. The most common attempted methods of suicide differ from the most common methods of completion; up to 85% of attempts are via drug overdose in the developed world.
In China, the consumption of pesticides is the most common method. In Japan, self-disembowelment known as seppuku (or hara-kiri) still occurs;however, hanging and jumping are the most common. Jumping to one’s death is common in both Hong Kong and Singapore at 50% and 80% respectively. In Switzerland, firearms are the most frequent suicide method in young males, however this method has decreased relatively since guns have become less common. In the United States, 57% of suicides involve the use of firearms, with this method being somewhat more common in men than women. The next most common cause was hanging in males and self-poisoning in females. Together, hanging and poisoning constituted about 40% of U.S. suicides (as of 2005).
There is no known unifying underlying pathophysiology for either suicide or depression. It is however believed to result from an interplay of behavioral, socio-environmental and psychiatric factors.
Low levels of brain-derived neurotrophic factor (BDNF) are both directly associated with suicide and indirectly associated through its role in major depression, posttraumatic stress disorder, schizophrenia and obsessive–compulsive disorder. Post-mortem studies have found reduced levels of BDNF in the hippocampus and prefrontal cortex, in those with and without psychiatric conditions. Serotonin, a brain neurotransmitter, is believed to be low in those who die by suicide. This is partly based on evidence of increased levels of 5-HT2A receptors found after death. Other evidence includes reduced levels of a breakdown product of serotonin, 5-Hydroxyindoleacetic acid, in the cerebral spinal fluid. Direct evidence is however hard to gather. Epigenetics, the study of changes in genetic expression in response to environmental factors which do not alter the underlying DNA, is also believed to play a role in determining suicide risk.
Suicide prevention is a term used for the collective efforts to reduce the incidence of suicide through preventative measures. Protective factors for suicide include support, and access to therapy. About 60% of people with suicidal thoughts do not seek help. Reasons for not doing so include low perceived need and wanting to deal with the problem alone. Despite these high rates, there are few established treatments available for suicidal behavior.
Reducing access to certain methods, such as firearms or toxins such as opioids and pesticides, can reduce risk of suicide by that method.This may be in part because suicide is often an impulsive decision, with up to 70% of near-fatal suicide attempts made after less than one hour of deliberation—thus, reducing access to easily-accessible methods of suicide may make impulsive attempts less likely to succeed. Other measures include reducing access to charcoal (for burning) and adding barriers on bridges and subway platforms. Treatment of drug and alcohol addiction, depression, and those who have attempted suicide in the past may also be effective. Some have proposed reducing access to alcohol as a preventative strategy (such as reducing the number of bars).
In young adults who have recently thought about suicide, cognitive behavioral therapy appears to improve outcomes. School-based programs that increase mental health literacy and train staff have shown mixed results on suicide rates. Economic development through its ability to reduce poverty may be able to decrease suicide rates. Efforts to increase social connection, especially in elderly males, may be effective. In people who have attempted suicide, following up on them might prevent repeat attempts. Although crisis hotlines are common there is little evidence to support or refute their effectiveness. Preventing childhood trauma provides an opportunity for suicide prevention. The World Suicide Prevention Day is observed annually on September 10 with the support of the International Association for Suicide Prevention and the World Health Organization.
There is little data on the effects of screening the general population on the ultimate rate of suicide. Screening those who come to the emergency departments with injuries from self harm have been shown to help identify suicide ideation and suicide intention. Psychometric tests such as the Beck Depression Inventory or the Geriatric Depression Scale for older people are being used. As there is a high rate of people who test positive via these tools that are not at risk of suicide, there are concerns that screening may significantly increase mental health care resource utilization. Assessing those at high risk however is recommended. Asking about suicidality does not appear to increase the risk.
In those with mental health problems a number of treatments may reduce the risk of suicide. Those who are actively suicidal may be admitted to psychiatric care either voluntarily or involuntarily. Possessions that may be used to harm oneself are typically removed. Some clinicians get patients to sign suicide prevention contractswhere they agree to not harm themselves if released. Evidence however does not support a significant effect from this practice. If a person is at low risk, outpatient mental health treatment may be arranged. Short-term hospitalization has not been found to be more effective than community care for improving outcomes in those with borderline personality disorder who are chronically suicidal.
There is tentative evidence that psychotherapy, specifically, dialectical behaviour therapy reduces suicidality in adolescents as well as in those with borderline personality disorder. It may also be useful in decreasing suicide attempts in adults at high risk. Evidence however has not found a decrease in completed suicides.
There is controversy around the benefit-versus-harm of antidepressants. In young persons, some antidepressants, such as SSRIs, appear to increase the risk of suicidality from 25 per 1000 to 40 per 1000. In older persons, however, they might decrease the risk. Lithium appears effective at lowering the risk in those with bipolar disorder and unipolar depression to nearly the same levels as the general population. Clozapine may decrease the thoughts of suicide in some people with schizophrenia. Ketamine, which is a dissociative anaesthetic, seems to lower the rate of suicidal ideation. In the United States, health professionals are legally required to take reasonable steps to try to prevent suicide.
Suicide rates differ significantly between countries and over time. As a percentage of deaths in 2008 it was: Africa 0.5%, South-East Asia 1.9%, Americas 1.2% and Europe 1.4%. Rates per 100,000 were: Australia 8.6, Canada 11.1, China 12.7, India 23.2, United Kingdom 7.6, United States 11.4 and South Korea 28.9. It was ranked as the 10th leading cause of death in the United States in 2016 with about 45,000 cases that year. Rates have increased in the United States in the last few years, with the highest value being in 2017 (the most recent data). About 650,000 people are seen in emergency departments yearly due to attempting suicide. The country’s rate among men in their 50s rose by nearly half in the decade 1999–2010. Lithuania, Japan and Hungary have the highest rates. Around 75% of suicides occur in the developing world. The countries with the greatest absolute numbers of suicides are China and India, accounting for over half the total. In China, suicide is the 5th leading cause of death.
Sex and gender
China has one of the highest female suicide rates in the world and is the only country where it is higher than that of men (ratio of 0.9). In the Eastern Mediterranean, suicide rates are nearly equivalent between males and females. The highest rate of female suicide is found in South Korea at 22 per 100,000, with high rates in South-East Asia and the Western Pacific generally.
A number of reviews have found an increased risk of suicide among transgender, lesbian, gay, and bisexual people. Among transgender persons rates of attempted suicide are about 40% compared to a general population rate of 5%. This is believed to in part be due to social stigmatisation.
In many countries the rate of suicide is highest in the middle-aged or elderly. The absolute number of suicides however is greatest in those between 15 and 29 years old, due to the number of people in this age group. Worldwide, the average age of suicide is between age 30 and 49 for both men and women. This means that half of people who died by suicide were approximately age 40 or younger, and half were older. Suicidality is rare in children, but increases during the transition to adolescence.
In the United States the suicide death rate is greatest in Caucasian men older than 80 years, even though younger people more frequently attempt suicide. It is the second most common cause of death in adolescents and in young males is second only to accidental death. In young males in the developed world, it is the cause of nearly 30% of mortality.In the developing world rates are similar, but it makes up a smaller proportion of overall deaths due to higher rates of death from other types of trauma. In South-East Asia, in contrast to other areas of the world, deaths from suicide occur at a greater rate in young females than elderly females.
In ancient Athens, a person who committed suicide without the approval of the state was denied the honors of a normal burial. The person would be buried alone, on the outskirts of the city, without a headstone or marker. However, it was deemed to be an acceptable method to deal with military defeat. In Ancient Rome, while suicide was initially permitted, it was later deemed a crime against the state due to its economic costs. Aristotle condemned all forms of suicide while Plato was ambivalent. In Rome some reasons for suicide included volunteering death in a gladiator combat, guilt over murdering someone, to save the life of another, as a result of mourning, from shame from being raped, and as an escape from intolerable situations like physical suffering, military defeat, or criminal pursuit.
Suicide came to be regarded as a sin in Christian Europe and was condemned at the Council of Arles (452) as the work of the Devil. In the Middle Ages, the Church had drawn-out discussions as to when the desire for martyrdom was suicidal, as in the case of martyrs of Córdoba. Despite these disputes and occasional official rulings, Catholic doctrine was not entirely settled on the subject of suicide until the later 17th century. A criminal ordinance issued by Louis XIV of France in 1670 was extremely severe, even for the times: the dead person’s body was drawn through the streets, face down, and then hung or thrown on a garbage heap. Additionally, all of the person’s property was confiscated.
Attitudes towards suicide slowly began to shift during the Renaissance. John Donne’s work Biathanatos contained one of the first modern defences of suicide, bringing proof from the conduct of Biblical figures, such as Jesus, Samson and Saul, and presenting arguments on grounds of reason and nature to sanction suicide in certain circumstances.
The secularization of society that began during the Enlightenment questioned traditional religious attitudes toward suicide and brought a more modern perspective to the issue. David Hume denied that suicide was a crime as it affected no one and was potentially to the advantage of the individual. In his 1777 Essays on Suicide and the Immortality of the Soul he rhetorically asked, “Why should I prolong a miserable existence, because of some frivolous advantage which the public may perhaps receive from me?” A shift in public opinion at large can also be discerned; The Times in 1786 initiated a spirited debate on the motion “Is suicide an act of courage?”.
By the 19th century, the act of suicide had shifted from being viewed as caused by sin to being caused by insanity in Europe. Although suicide remained illegal during this period, it increasingly became the target of satirical comments, such as the Gilbert and Sullivan comic opera The Mikado, that satirized the idea of executing someone who had already killed himself.
By 1879, English law began to distinguish between suicide and homicide, although suicide still resulted in forfeiture of estate. In 1882, the deceased were permitted daylight burial in England and by the middle of the 20th century, suicide had become legal in much of the western world. The term suicide first emerged shortly before 1700 to replace expressions on self-death which were often characterized as a form of self-murder in the West.
Social and culture
In the United States, suicide is not illegal but may be associated with penalties for those who attempt it. Physician-assisted suicide is legal in the state of Washington for people with terminal diseases. In Oregon, people with terminal diseases may request medications to help end their life. Canadians who have attempted suicide may be barred from entering the US. US laws allow border guards to deny access to people who have a mental illness, including those with previous suicide attempts.
In Australia suicide is not a crime. It however is a crime to counsel, incite, or aid and abet another in attempting to die by suicide, and the law explicitly allows any person to use “such force as may reasonably be necessary” to prevent another from taking their own life. The Northern Territory of Australia briefly had legal physician-assisted suicide from 1996 to 1997.
In India, suicide used to be illegal and surviving family could face legal difficulties. The Indian government repealed this law in 2014. It remains a criminal offense in most Muslim-majority nations.
In most forms of Christianity, suicide is considered a sin, based mainly on the writings of influential Christian thinkers of the Middle Ages, such as St. Augustine and St. Thomas Aquinas, but suicide was not considered a sin under the Byzantine Christian code of Justinian, for instance. In Catholic doctrine, the argument is based on the commandment “Thou shalt not kill” (made applicable under the New Covenant by Jesus in the Gospel of Matthew), as well as the idea that life is a gift given by God which should not be spurned, and that suicide is against the “natural order” and thus interferes with God’s master plan for the world. However, it is believed that mental illness or grave fear of suffering diminishes the responsibility of the one completing suicide.
Judaism focuses on the importance of valuing this life, and as such, suicide is tantamount to denying God’s goodness in the world. Despite this, under extreme circumstances when there has seemed no choice but to either be killed or forced to betray their religion, Jews have committed individual suicide or mass suicide (see Masada, First French persecution of the Jews, and York Castle for examples) and as a grim reminder there is even a prayer in the Jewish liturgy for “when the knife is at the throat”, for those dying “to sanctify God’s Name” (see Martyrdom). These acts have received mixed responses by Jewish authorities, regarded by some as examples of heroic martyrdom, while others state that it was wrong for them to take their own lives in anticipation of martyrdom.
Islamic religious views are against suicide. The Quran forbids it by stating “do not kill or destroy yourself”. The hadiths also state individual suicide to be unlawful and a sin. Stigma is often associated with suicide in Islamic countries.
In Hinduism, suicide is generally frowned upon and is considered equally sinful as murdering another in contemporary Hindu society. Hindu Scriptures state that one who dies by suicide will become part of the spirit world, wandering earth until the time one would have otherwise died, had one not taken one’s own life. However, Hinduism accepts a man’s right to end one’s life through the non-violent practice of fasting to death, termed Prayopavesa; but Prayopavesa is strictly restricted to people who have no desire or ambition left, and no responsibilities remaining in this life. Jainism has a similar practice named Santhara. Sati, or self-immolation by widows, is a rare and illegal practice in Hindu society.
A number of questions are raised within the philosophy of suicide, included what constitutes suicide, whether or not suicide can be a rational choice, and the moral permissibility of suicide. Arguments as to acceptability of suicide in moral or social terms range from the position that the act is inherently immoral and unacceptable under any circumstances, to a regard for suicide as a sacrosanct right of anyone who believes they have rationally and conscientiously come to the decision to end their own lives, even if they are young and healthy.
Opponents to suicide include Christian philosophers such as Augustine of Hippo, Thomas Aquinas, Immanuel Kant and, arguably, John Stuart Mill – Mill’s focus on the importance of liberty and autonomy meant that he rejected choices which would prevent a person from making future autonomous decisions. Others view suicide as a legitimate matter of personal choice. Supporters of this position maintain that no one should be forced to suffer against their will, particularly from conditions such as incurable disease, mental illness, and old age, with no possibility of improvement. They reject the belief that suicide is always irrational, arguing instead that it can be a valid last resort for those enduring major pain or trauma. A stronger stance would argue that people should be allowed to autonomously choose to die regardless of whether they are suffering. Notable supporters of this school of thought include Scottish empiricist David Hume and American bioethicist Jacob Appel.
Advocacy of suicide has occurred in many cultures and subcultures. The Japanese military during World War II encouraged and glorified kamikaze attacks, which were suicide attacks by military aviators from the Empire of Japan against Allied naval vessels in the closing stages of the Pacific theater of World War II. Japanese society as a whole has been described as “suicide-tolerant”.
Internet searches for information on suicide return web pages that 10–30% of the time encourage or facilitate suicide attempts. There is some concern that such sites may push those predisposed over the edge. Some people form suicide pacts online, either with pre-existing friends or people they have recently encountered in chat rooms or message boards. The Internet, however, may also help prevent suicide by providing a social group for those who are isolated.
