I don't believe that the threat of death would stop the one who is not stopped by the threat of life imprisonment. Those who make "anti-human" crimes usually either do not care of the consequences or do not believe to be punished at all. On the other hand when the threat of being captured becomes very real they can become even more dangerous both to those who are going to arrest them and to people around. More danger, more deaths.

It is right by itself, but it can not be the direct purpose of the punitive machine. This machine is more dangerous than all subhumans together and needs much caution, exact objective and non-emotional rules to function.
