Altruistic suicide? A clay sculpture of a suicide bomber is displayed at a Baghdad art gallery. Some sociologists believe that the acts of such bombers fit Durkheim’s definition of altruistic suicide, arguing that the bombers believe they are sacrificing their lives for the well-being of their society. Other theorists, however, point out that many such bombers seem indifferent to the innocent lives they are destroying and categorize the bombers instead as mass murderers motivated by hatred rather than by feelings of altruism (Humphrey, 2006).
