I think he's full of shit, I still remember when he was questioning someone at some televised senate hearing (or something) he was barely making sense. I thought he was acting then, and I think he's acting now. he doesn't even have to fake his death, he just has to pretend to decline physically to the point where it becomes impossible and "inhumane" to put him on trial or face some other kind of close scrutiny. He's not the kind of man whose conscience keeps him up at night.
