You're looking at history books written by the victors who claim he's the 2nd in line behind Satan.

Which ones do you mean? And how exactly do you know they are wrong? Just because they were supposedly "written by the victors"? Of course, you don't have any problems trusting the most outrageous claims about the USSR "written by the victors", so you are not exactly consistent.

Did Hitler destroy the Arch de Triumph? The Louvre? Countless other priceless things?

Paris was declared an open city. Same for Rome. Talking about historical illiteracy.

or did the Germans actually try to avoid collateral damage?

They most certainly didn't. Especially not in the USSR. Of course, you either want to ignore all that, or to pretend that it's good to kill Russian peasants because they had earlier suffered under communism.

Maybe they weren't these 100%, irredeemably evil, 1 dimensional caricatures that pop culture paints them to be.

Neither was Stalin. Doesn't mean that he was a good guy like you pretend. And in fact, the history books you've never read point this out.

Why did you put it in quotation marks?

Because it was the Soviet Union.

Was it worse to any degree in your opinion? Their death count was unarguably higher.

Of Stalin? How do you come to that conclusion? By ignoring all the wars? And I'm curious how you got at the "15x". Not taking any issue with that specific number, but you clearly mean 'way worse'.
