Beyond the cognitive and emotional state is actual aggression, or attacking someone or a group. It's intent is to harm. Fantasies of aggression often precede actual acts. Hostility is a permanent of anger and antipathy toward people. Rage is when anger, which is episodic, explodes into completely irrational behavior, as in road rage.
Frustration can be more legitimate and productive.
We are disappointed in ourselves or others, and wish for a different outcome. Frustration may result in positive change or, if it does not result in positive change, it could morph into anger, hostility or rage. Assertiveness is different than aggression, and suggests proactive dealing with facts and circumstances in a rational fashion. However, aggression can be cold and calculating. When our aggression results in a complete loss of control and rationality, it becomes rage.
