What a though topic!!
Emotionally the first thing that comes to mind is "never let him meet a child again"... Especially when you think that child could be yours...
I also had some friends who were abused as children so it's easy to think "lock him up forever!!!"
But then... As far as I know, abusers are almost always ex-abused children, right? So to think there's no hope for them to come out of it is somewhat equal to saying there's no hope for abused children, too. And this is simply unacceptable.
I think it should be decided case by case, and with a lot of thinking and care too. Not an easy thing to decide, really.
