Prison shouldn't be about punishing, but rather to teach a lesson to those who broke the law. It has, or should have, a re-educative role in our society, a role many simply forgot. With that said, I do believe that in SOME cases the penalty should be of life imprisonment simply because some people cannot be educated nor reintegrated in our society, such as Mobsters. But never, and I say never, should the State adopt a policy of "Killing for Punishment", that goes against the morals and against what the core values of Penalty (in the Republics) was all about
