"Bullies are typically attempting to promote or assert an identity rather than defend one. Their behavior is typically predatory rather than dispute related. Bullies prey on vulnerable targets, usually in the presence of third parties, in order to show how tough they are (see Olweus, 1978). For the bully, dominating the victim is an accomplishment, a way of demonstrating power to himself and others. In case of jealousy, a person may intentionally harm another person who has not attacked or wronged them in any way. Both justice and self-image concerns can produce an aggressive response when someone is jealous. When people think that someone has received an unfair share of some reward, they may attempt to restore equity by harming the person, even when that person is not held responsible for the injustice. We have referred to this behavior as "redistributive justice" (to distinguish it from "retributive justice"). Thus, an employee may blame the supervisor who gives a raise to someone else but attempt to produce unfavorable outcomes for the coworker who received a raise. Jealous people may also attempt to harm the object of jealousy for purposes of downward comparison (Wills, 1981). They may engage in aggressive behavior that lowers the standing of the target on some dimension, thereby providing a favorable comparison for the actor. They put themselves "up" by putting others "down". Wills (1981) suggested that downward comparison was an alternative explanation for the displacement effects obtained in experiments testing frustration-aggression theory. He noted that investigations of displaced aggression, scapegoating, and hostility generalization all involve some challenge to the participants' identities."
