People that break the constitution in favor of money don't really deserve to be given a judgment based on our constitution. They broke not only that, but endangered the existence of said constitution.
We don't kill murderers, yes, they kill at worst a handful of people. We do kill terrorists when they have weapons on hand to kill civilians. High treason is just terrorism with informations.
Let's be real, you would be against life without parol in that case as well. I would be ok with that, i just don't see how its economically viable. People trying to destroy our state shouldn't get a life financed by our state. And the current laws are obviously not punishing enough.
