Oddly, I feel sorry for him. Well, sorry for him if he is aware of the humiliating shame that must come now that his addiction is known. I always thought he was... a jerk! nothing more or less. Not a very interesting jerk either. I don't think his being a jerk had anything to do with his becomming a Vicodin addict.
Addiction is a terrible thing to be inflicted with. Whether it's self infliction or not doesn't matter once that monkey is on your back.
That's a hell I'd wish on NO-ONE.
Maybe he'll become a more thoughtful person after he has fought this off. I hope he CAN fight it. I think, though, that he really hasn't the inner strength he'll need.
