I have been an Earl fan since mid eighty's so I have thought about his actions for a long time. Seems to me the one thing that makes him a great player is also what makes him go off. That is his over self confidence. He expects to make every ball and to be in dead stroke all the time and when he is not, he looks for excuses. he is so used to winning that it is really painful. He also sees the end coming and it is more important to perform good until he can't. I really believe he is a genius at pool and like many genius or savants have a people problems.
