Wow that's really harsh.
I really hate drugs and the harm they do.
But putting this guy in prison for the rest of his life won't end drug abuse.
I think the murder for hires were a bigger wrong committed. He defiantly deserves prison but I would let him out in his mid 60s. Earlier if he convinced all the staff he wanted to go back out into the world and just be with his family and live a normal life.
