While most of the time the emotion of anger appears to be destructive and antisocial, there is a case to be made that anger can be helpful to oneself and others. Explain.

a. One line of explanation is that anger is adaptive because it motivates people to act aggressively and assertively, thereby eliciting certain behaviors. It helps people to defend themselves and others, to pursue certain (blocked)goals, etc.
b. A second view suggests that anger serves to warn friends and family that aggression is potentially imminent. This gives people a chance to resolve conflicts before they escalate. The expression of anger may therefore (ironically)result in an overall reduction of aggressive behavior.
