should punishment for rapist be more than prison?
Rapists do get more punishment than just prison. There's a sort of hierarchy in prison, at the top you have murderers and lifers, it goes down to armed robbers and gangbangers, then on the secon-to-last rung is rapists. Below them, child molesters. They're the first ones to get raped in prison, and frankly, I don't lose any sleep over that.
Like young prepubescent girls? Be detailed please. If their prepubescent than you better learn how prisons treat such scum. Murders have a soft spot for kids that should tell you something. Prisons usually let the inmates if they asked what a certain inmate did to get in. And child molesters are usually castrated and killed the moment their found to be child molesters.
I would say they get what they deserve already.
