Anger is one thing, violence another.  — Count Fenring to Baron Harkonnen

My Take – We all feel anger.  It can be a minor irritation or it can be red-tinged tunnel vision and everything in between.  The key is to control your anger before it overtakes your reason.  If violence is necessary, try to do it without allowing your passions, either fear or anger, driving you to it.  “He pissed me off” is rarely a good excuse, as much as we would like it to be sometimes.
