My dad was that way too except he didn't need alcohol for his violent outbursts. He was never wrong in his life. He could always justify what he did in some way or another. He also was very liberal with curse words and insults to us. Constantly insulting us, putting us down. I finally realized that he was the one with the problem. He has never admitted that he has a problem, and never will. He is 63 now and has mellowed a bit, but the problem still shows up occasionally.
