It is important to look first at what anger is and its relationship to aggression or aggressive behaviour.
Anger is an emotion or feeling.
There has been difficulty pinning down exactly what we mean by an emotion or feeling. That is because a feeling is such an abstract term. And also because it is difficult for most people to express their feelings in adequate words and for us to fully understand someone else s feeling. Anger can also be described as a natural response to displeasure and frustration. Aggression, on the other hand, is the behavioural manifestation of such a feeling, that causes physical or mental injury to another or damage to property.
