After taking his money, after punking him with the girl, after punking him for using his club. You can only take it up the ass so much, so he pretty much chose to die on his feet at that moment. Not a smart move, but i understood where he was coming from with it. Plus i don't think he forgot about them as much as he didn't think they would factor into this since he was skipping town. There was no move for him to make with them.
