This has been a problem that is being looked at where I live. The civil commitment of these offenders is really expensive and it is felt that at some point it will be waaaaay to expensive to continue, so they want to release some of these monsters with monitoring and bracelets. So far, no go, but I am very scared because these monsters have lawyers working on it.
There has been discussion that you don't want to make it so they can't have a lesser penalty if they keep the child alive.
It is felt that if the penalty is too severe, the monsters will kill the child. Nothing to lose.
They say that they kill the children not because they enjoy the killing, but it is to leave no witness.
I really feel a one time offense and you are locked up forever and ever.
Then there is no worry about escalation. I posted an article earlier that talks about how the average molester molests 400-800 times.
Whether they can be rehabbed or not does not enter into to it for me. They are done, as far as I a concerned. They have destroyed another's life who will need years of therapy, probably.
If you choose to drink and drive and hit a tree and become a paraplegic, there is no do over. If you rape someone, there is no do over.
