One sentence that throws the problem of evil out of the window.

Then by that logic, if Hitler thought he was doing Gods will, doesn't that absolve him of any blame? Whether or not he believed it, in many instances he profiled himself and his movement Christian, catholic even, and doing the lord's bidding. Could've been lying and manipulative about it, , but he could have honestly been convinced that what he was doing was God's work. I'm pretty sure he thought it was necessary and right, in his mind in any case. And even if he didn't believe he was followign the lord's command, by profiling his movement as such those in the Nazi party under him who believed in the Christian God found justification for their actions. They probably did heinous things whilst believing it being a holy cause.Just like the crusades of old or even muslim terrorism today.

Or look at it this way. If Abraham had been mistaken. If the devil, supposedly the greatest cheater and lying monster (though created purposefully such by God but that's a rant for another day) had convinced Abraham he was God and that he ordered him to sacrifice his son; would Abraham's culpability still be mitigated? After all, in his heart as honest as could be, he'd still think he was following divine guidance.

If Hitler was insane and hallucinating and hearing a voice telling him to kill millions of people, his culpability probably would be mitigated as well. Id say for reason of insanity. Which is why, as i said, i cant say for sure that hes in Hell. I can make a guess, but cant claim anything. But I highly doubt that was the case. He may have claimed he was doing Gods work in order to get followers or whatever, but I highly doubt he genuinely heard a voice he believed to be God's telling him to kill people.

I don't think one has to think God gives specific talks to you to think you are doing his will. I don't think every catholic nazi, every jihadist, every Westboro baptist church hatemonger, every christian klu klux klan member, ... that did horrible things in the name of God thought God spoke to them specifically. Same could have been with Hitler, without it being a sign of what we lable insanity.

For instance, you may not think God speaks to you directly, right? But I'm guessing you do have your notion of what your God expects you to do. Same concept, just far less extreme. You have your own idea of a Godly life and live by it, accordingly. In your case it just might be rather benign
But that's one of the great problems a lot of atheists have with religion. If you believe God is on your side, in agreement with your preconceived notions aqcuired through your social and natural surroundings and your own genetic make-up as wel as your upbringing, anything becomes excuseable. As long as it is in the name of the lord, nothing is truly evil. Including trying to gut your own son atop a mountaintop.

Praise be Him.
