Deadly Companions by Sam Peckinpah
"You don't know me well enough to hate me that much. Hating is a subject I know a little something about. You got to be careful it don't bite you back. I know somebody who spent five years looking for a man he hated. Hating and wanting revenge was all that kept him alive. He spent all those years tracking that other man down, and when he caught up with him, it was the worst day of his life. He'd get his revenge all right, but then he'd lose the one thing he had to live for."
