Altruistic suicide describes when individuals kill themselves in order to benefit other people.
Altruism is social behavior that means doing good for the sake of others. Altruistic suicide was a concept first identified by Emile Durkheim and is when a person commits suicide in order to benefit others. Altruistic suicide is sometimes viewed as a courageous act such as self-sacrifice during times of war.
For example, a soldier jumping on a grenade in order to save others yet kills him would be a form of altruistic suicide. Sometimes individuals will commit altruistic suicide when they are facing a terminal illness because they believe it will be better for their friends and family.
