As I see it if he had not right to kill anyone, anyone had the right to kill him. I dont believe in hell so for me they just released him from a lot of pain he should have suffered in prison. Anyway about the 90% of the world primer ministers, presidents, war ciefs have done the same thing (some even worse) and I wont live to see them pay for it so talking about justice just makes me feel sad.
It was their decision, imo they chose the wrong one.
