No, but being locked up for life does, unless he does it in prison.
Punishment my behind, the reason he's in jail is not a punishment, it's to take him out of the society so we can live safely.
No punishment is going to reform this man, and we can be cruel to him, but in the end it serves no purpose anymore, he's stuck in jail, forever, he won't harm anyone anymore.
The desire for revenge is something we shouldn't give into, it's a bad thing to give into.
I'm not defending this man, but geez, torturing prisoners is something we shouldn't start doing.
