he's a good guy on the wrong side of the tracks, in a world being overthrown by chaos. one man... can stand before the world and give his proclamation of love to the world that has shunned him in his time of need.
seriously though, he's a good guy with a drug problem. if he really is and stays clean, then good for him and if not, then not as good for him. either way, his life is his life and as sion has said, the guy has given boatloads of cash to charities WITHOUT turning into a media whore about it. also, there's a reason that there are talks about him being resigned to the show.
