There are three different types of aggression: instrumental aggression, reactive aggression, and relational aggression.  One way to classify aggression is by its motive.  Instrumental aggression is the name for hurtful behavior that is actively initiated to achieve a goal.  example:  Dayonna kicks Gonzo to gain possession of the basketball or Tynell spreads a rumor about Iberia to replace her as Pam’s best friend.
