It has been written by people who knew him that he was becoming disillusioned by liberals and the hippie movement. Who knows, by now he could have been just as conservative and wise as anyone here.
That is always a possibility. But I don’t think so, I think everyone around him would have exiled him if so. Don’t think he would have done that.
He was a revolutionary, if he had the chance, he would have overthrown the UK/US governments without hesitation. I think, that is one of the reasons he was killed. His voice reached millions, much like MLK. Once a public speaker/celebrity starts spouting about revolution on the level that MLK and Lennon did, then they get taken out. Sometimes I think this is the truth, other times I think opposite. Dunno.
