At the risk of alienating folks here, I'll note that the classic example of this would be Saint Paul, though of course his persecutions were nowhere near the holocaust.

What I do detest is: let's be a bitch now with abandon, I will have plenty of time to reform, repent, and do penance later. The implicit permission to be evil NOW

@JussiVilleHeiskanen What a flip-flopper I am. I remember some years ago thinking that one should sin freely and trust in grace. I am a muppet.

Think it would be crucial that nobody knew there was a blue button though.

Is there any argument for red other than vengeance?

@TheAllMemeingEye You could argue even if Hitler becomes a genuinely good person after pressing the button he'd get killed at that point anyway. Assuming a 'pardon for his previous wrongdoings' means just an official pardon it's likely some of his victims unhappy with this decision would seek retaliation and assassinate him. By pressing the red button you prevent a good person being killed.

I'd press blue because I think what the picture meant was a 'aww he became so sweet and remorseful after the genocide, let's let him atone' brainwashing kind of pardon.

@TenShino hmm, maybe, although it's worth noting that many ousted dictators have got away basically scot free e.g. Hirohito, Pol Pot, Idi Amin, Mengistu, Stroessner, and many more. It seems plausible that a redeemed Hitler could prove so useful for denazification that Allied governments may protect him from retaliation.

Traveling to the moment when he's about to kill himself anyway is pointless.

Any parent can tell you that the real dilemma would be killing the baby Hitler vs raising him a good man.

I don't think either button is really necessary since the guy died in 1945
