Punishment has to be about protection for the people and about rehabilitation of the individual. Don’t forget the pedophile has no choice in his proclivities. So getting him to make healthy safe choices is the goal and protecting children from him. Not killing him, but storing him safely is not about his wellbeing but about keeping the rest of society acting humanely. People here talk about basic income all the time. Not being humane is a slippery slope for society, and the cost of not entering it is very much worth it.
