Anyhow, it depends what aspect of child abuse.
I think that child rapists deserve life in prison. Period. I think that those stupid probation comittees also ought to be kept out of the matter.
"It's a disease though, you heartless jerk!"
Well, disease or not, we all have the ability to control our actions, and if someone rapes and/or kills a kid, then that person is evil. Period. I mean, sure we all have kinda "off" desires sometimes, but that's no excuse to act on them.
And as for the "second chance, you heartless jerk" argument, all I have to say is that they've permanently damaged a child for the rest of their life (or even took away their life), and that's deserving of being locked up forever.
Now as for simple violence against a child, certainly jail time should be a must, IMO. Although no harm in giving your kid a "spanking" or a little whap on the head as a reminder, but when it gets brutal and overly violent, you're talking about a serious offense.
I have no tolerance for those who abuse children, and no one else should either.
EDIT: And for multiple offenses of child rape/murder, capital punishment ought to be the answer.
