Control-reaction is my own term for a description of a source of anger. Quite often small children learn that they can control the situation through anger if their parents don't stop them. The picture is that Johnny has a temper tantrum to get what he wants. In marriage, he may use anger to control his wife and children. Anger become a means of manipulation.
Anger become a necessary friend.
At times we don't see the big picture. We may take one look at the situation and declare that God is unfair. This view often produces anger. David became very distressed when he saw the wicked prosper. Jonah became very angry because he thought that God was unfair.
