Aggression is a product of the instinctual “fight or flight” response, with the “fight” aspect being the root of aggressive behavior. Aggression is a pervasive force that distorts human interactions, often masked by social norms or justified as “righteous anger”. Aggression can also be chanelled towards felicitous means.
