I heard the ending, how he's apparently raped then stabbed in the asylum.

This is the same with EVERY MALE character they write to be the villian but the audience latches onto. They need to 'kill' that character to essentially go 'you can't like him, you should hate him or we'll systematically destroy him!'

Fortunately they've done it enough times that the genera audience is wise to it and won't put up and watch it going by box office returns.
