There is a critically important point to understand about violent people. They are trapped in a world that is all about them. By this we don’t just mean they are egomaniacal, they very narcissistic in their world view (up to and including Narcissistic Personality Disorder among other things). All the average person sees is the violence. What you don’t see is the intense self-loathing, chronic anger, warped perceptions, fear, paranoia, blaming behavior and other demons that drive these people. And the reason you don’t see this is because they are either deeply hidden beneath layers upon layers of self-rationalization or because, at ground zero, you’re too busy experiencing the blast to see it clearly.
Now knowing this, it should be easier to understand that to such a personality how one “looks” if even more important than life itself. By looks, we don’t just mean physical appearance. We are talking how one appears in the eyes of others. Others who are — at least in the violent person’s worldview — always waiting to prey upon the first sign of weakness. If that person displays weakness, in his mind, he’s next on the dinner plate. As such they are hyper-sensitive to insults and loss of ‘face.’ Truth is, this program is always running, whether there are witnesses or not. However, if there are witnesses, this program is given an octane boost. In certain lifestyle, a ‘man getting his props’ (proper respects) is more important than his life.
He has some good advice.
