I oppose the death penalty but make an exception for war criminals, same way I would for the Nuremberg Trials.
Why should serial killers like Jeffrey Dahmer get a second chance, but not Putin? Sure Putin has caused more damage than Dahmer, but that’s because he’s in a major position of power. Putin is a horrible person, but none of his actions are quite as morally depraved as Dahmer, who murdered and cannibalized dozens of people. I understand that your biggest reason for opposing the death penalty is because there’s a chance the person is innocent, but with cases like Putin and Dahmer, where there guilt is undeniable and their actions are reprehensible enough to justify a death sentence, there is no logical reason to not execute them.
I think that you should not only carve out an exception for war criminals, but also for mass murderers whose guilt is undeniable
