We all have human emotions. And anger is one of them. Anyone, and I mean anyone, can be caused to not only have anger. But to follow through in retaliation at the peak of anger.
Most people have learned how to control their anger to a point. But beyond that point. It is not good.
I myself have been very angry at times. Lucky for me. I didn't follow through. It was so close though at times. But, I understand the angry emotion as most of us should.
