Despite how little sense the way the second amendment was followed in this country makes to me, still, those who argue that there should be no death penalty, and not because of the issue of the certainty of the guilt, to me, speak tongue. However it is the much bigger effect of the first matter that makes me prioritize it.
Not only the "cruel and unusual punishment" in the constitution has nothing to do with the death penalty for killers, it has nothing to do with an eye for an eye system in general. Aside from other things, if it is, why does the fifth amendment speaks about jeopardy of "limb"?
The good news is that the world is now relatively much better in accounting for victims regardless of their color, religion, gender and the like. The bad news is that much of what was abandoned there got replaced by even stupider argument to waste the rights of victims. Actually, it could be even closer to contradictory than stupid. It is an argument that is much more from its face logically intolerable because it prefers aggressors over victims merely because of being in those positions.
