Understanding Anger and Aggression
Anger can be the result of hurt pride, unreasonable expectations or repeated hostile fantasies. We may unconsciously use anger to blame others for our own shortcomings, to justify oppressing others, to boost our own egos, to conceal other feelings and to handle other emotions.
Any situation that frustrates us (especially when we think someone else is to blame) can potentially trigger anger and aggression. Frustration can lead to anger, and anger can lead to aggression.
