I'm even more certain that David WOULD punch his brother. aside from what we saw on screen with Anton, I'm sure that having lived in Jame's shoes for a period of time would have exposed David to the type of man his brother became. That alone would likely elicit that reponse. Yes, David is forgiving, and would probably make peace with James, but the initial punch in the face is so totally in character.
