The fire burns within: Individual motivations for self-sacrifice.

Extreme self-sacrifice in intergroup conflict may be driven not only by situational factors generating "fusion," but also by interindividual differences. Social value orientation is discussed as a potential contributor to self-harming behavior outside of intergroup conflicts and to the general propensity to participate in intergroup conflict. Social value orientation may therefore also be a person-specific determinant of extreme self-sacrifice in intergroup conflict.
