Forgive, but NEVER forget. I would never give the creep another opportunity! Castration is the answer.
Of course my neighbor has her own little girl. I told her never ever let her daughter get near him and she said "Oh, he wouldn't do it anymore"
Sorry, you are deluding yourself if you think that castration will stop a pedophile. Even if it keeps an erection from occurring, which is NOT a given, the sickness in the head makes them do other forms of molestation. There is a lot of molestation that is not actual intercourse.
The sick facination with children does not go away with the removal of the family jewels.
You have two choices to be certain. Execution, or permanent incarceration.
