Please don’t rephrase me so it’s easier to argue.
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.
I’m sure that if needed, society can develop necessary framework (declare them “legally dead” or something like that).
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
