Even if there was hard solid evidence for Ched being an extremely violent, thuggish rapist, he'd still be forgiven by people in a few years. Look at the likes of Chris Brown. He beat his girlfriend to a pulp, there was hard evidence for it, he didn't go to prison, and his music career has gone absolutely through the roof without him showing any signs of remorse whatsoever. He even won a bloody grammy and nobody (to my knowledge) suggested it to be taken off him. Society is utterly depressing.
Or you could say it's more civilised. Someone commits a crime, they do their sentence/pay their debt to society and, when they have done this, they should be free to carry on with their lives and not be punished for evermore.
