Let me slip in before I'm too late...

I'm assuming the person actually sexually molested the child and actually acted on their impulses.

Depending on the severity/grossness of the crime, I'd say that a long jail term and psychiatric treatment could be appropriate for the most minor offenses. For more disgusting offenses... this may sound "cruel and unusual" and it probably is, but I think one of the best ways to deal with this is not necessarily to remove the urges, but to remove the means... you know... dismemberment where it hurts. In addition to jail time. Most child molesters are men... as a guy I know how awful such a punishment would be, but I'd say they certainly earned it. Same thing should happen with most rapists.

If what they did was really completely and indescribably nasty, then I'd say dismemberment then death.
