Answer to Question 2
Prosocial behavior and aggressive behavior actually overlap in some ways and are not clearly opposites. Both prosocial behavior and aggression can be used for the good of a group or others. Consider a football game in which a football player must engage in some level of aggression to win the game, but this is an act for the good of the team. People may use both aggression and prosocial behavior to gain status and popularity. A teacher or coach who aggressively punishes students or athletes by making them do extra work may actually be helping the students or athletes to improve their skill sets.
