I consider the risk of wrongful conviction to be an argument against the death penalty and for the very same reason I'm against performing any kind of inhuman treatment of them (which might be worse than death).

Even if 95% would totally deserve it, I don't think we should just accept that on average 4 innocent people every year are just treated as subhumans just so we can unleash our wrath over those who did truly horrible things.

Death is still a better option rather than being used as lab rat

> I am not talking about generic inmates, who deserve all protection (“no cruel and unusual punishment”), I’m talking about people like ones from the website. Who did horrible stuff and were convicted to death for it.

The most horrible people, some of whom were actually innocent?

I understand your emotional desire to (indirectly) hurt them, but the fact is that we can never be 100% sure that they were fully guilty of the acts exactly as described and everyone else in the world was completely innocent.

This means there is a nonzero chance of a miscarriage of justice, and you can't exactly un-execute someone. The only question remaining is: how many tortured and/or killed innocent warrant one monster not being harmed quite as much as your desire for revenge would like?
