Suicide in Jewish Tradition and Literature
Suicide is deemed a grave sin, yet Jewish legal authorities are alert to mitigating circumstances.
Those who take their own lives are technically not entitled to Jewish burial and mourning rites--but suicide as a freely chosen act (with the above consequences) has been nearly defined out of existence by mental health considerations in the development of Jewish law, and in most cases deaths by suicide are treated like all other deaths. Excerpted with permission from The Jewish Religion: A Companion, Oxford University Press.
In Jewish teaching, the prohibition of suicide is not contained in the sixth commandment: "Thou shalt not kill" (Exodus 20: 13 and Deuteronomy 5: 17). Obviously it does not follow from the fact that a man may not take the life of another that he may not take his own life.
There is, in fact, no direct prohibition of suicide in the Bible. In the Talmud (Bava Kama 91b), however, the prohibition is arrived at by a process of exegesis on the verse: "and surely your blood of your lives will I require" (Genesis 9: 5), interpreted as: "I will require your blood if you yourselves shed it." It is possible that there is no direct prohibition because very few people of sound mind would be inclined to commit suicide in any event.
It follows from this that suicide and murder are two separate offenses in the Jewish tradition, as they are in most cultures. Suicide is not homicide and is not covered in the Decalogue [the Ten Commandments]. In the usual rabbinic classification of duties, homicide would be considered an offense both "between man and God" and "between man and man," whereas suicide would fall only under the former heading.
Maimonides' statement (Rotzeah, 2.2-3) that there is no "death at the hand of the court" for the crime of suicide, only "death by the hands of Heaven," is puzzling, since how could a suicide, no longer alive, be punished for the crime by the court?
In all probability, Maimonides formulates it in this way to distinguish between the two crimes of murder and suicide. Maimonides' statement that a suicide is punished by the "hands of Heaven" no doubt refers to punishment in the hereafter; but the popular saying that a suicide has no share in the World to Come, which would cause a far more severe punishment to be visited on the suicide than on one guilty of murder, has no support in any of the classical sources. It has plausibly been suggested that the saying, though bogus, tended to be quoted as a warning to would-be suicides in stressful periods when there was a spate of suicides in the Jewish community.
Attitudes to Suicide
Suicide is considered to be a grave sin both because it is a denial that human life is a divine gift and because it constitutes a total defiance of God's will for the individual to live the life-span allotted to him. The suicide, more than any other offender, literally takes his life into his own hands. As it is put in Ethics of the Fathers (4. 21):"Despite yourself you were fashioned, and despite yourself you were born, and despite yourself you live, and despite yourself you die, and despite yourself you will hereafter have account and reckoning before the King of Kings, the Holy One, blessed be He."
