Well, he's dead. And although he was one of the biggest assholes I have ever heard of in terms of the sheer amount of hatred and bile he spewed (selections of which are included here and here), death is not something I would even wish on him. The best punishment for him is, in a sense, far worse: a deathbed realization of how ethically empty, wrong and utterly pointless his life was in engaging in this sort of shit for decade after decade.
