There has to be something in that guys past that made doing that OK with him! Abuse in the highest degree! I've burnt myself with a torch accidentally and it was no picnic! To hold one on a child's behind enough for third degree burns is sadistic. And points to something other than poor parental skills!
He definitely needs to be put away and some psychology is in order! I'd say death penalty but he would not suffer, and I really dont want to support him for 25 years waiting for it to happen.
I am a health care professional, and have had high level jobs in psychiatric hospitals. I have had a lot of exposure to people with mental and emotional problems. I have seen stories of horrific abuse. Sadly, this is the type of person that is sometimes the product of growing up in an abusive household.
But it does not always happen. There is more to what is inside a sadistic monster than psychiatric or emotional issues.
Deliberately torturing a living being, human or animal, is sadistic, depraved, and evil.
I think some of the worst monsters we know of, were not victims of an abusive childhood.
I do not feel sorry for this individual, and I hope justice catches up with him.
