Most social psychologists define aggression in terms of the intent and the purpose behind the behavior.  Aggression is intentional injury of or harm to another person. By this definition, the rapist is clearly acting aggressively, whereas the physician causing pain during a medical procedure is not.

Aggression is the behavior directed toward the goal of harming another living being.
