John was certainly flawed (who isn't), but I don't think that has to sit at odds with his peace thing. People criticise him for being a hypocrite over the Imagine lyrics - but all he's saying is IMAGINE a world without possessions, not lets all go live in a cave. And he could be moody and violent, but he's not Ghandhi or Mother Theresa. He was just a guy, his demons no suprise considering everyone he loved either died or left him, with high ideals. No more a hypocrite than anyone else I know.
