Critics aren't always so bad, but hate is too strong an emotion for someone like him I feel. I know about both of what you refer to, but he was cleared of all charges for the former for good reason. The "victim" even expressed how sad they were at his death and that they had been longtime friends. People will dig up any kind of negative information they can to make someone look bad, even in death which shows that we're quite a nasty society. I sincerely doubt any of these people took any time to look into his life or career to see that he isn't a nasty person whatsoever, nor is he a pedophile or a rapist.
And yes, he did make some nasty statements during 75/76 but the amount of cocaine he was taking was insane as you mentioned.
