Some of the WWII death was technically on Mussolini and the Japanese dictator, not all Hitler, which is why I didn't include the total war death toll, even though technically he did start the war. Btw, another thing our modern education will conveniently omit from discussing is that Hitler and Stalin had a pact where Stalin basically cut a deal with him and told him he could invade Poland without the USSR's interference, knowing that the last time someone had invaded Poland, england entered the war and it became WWI. This was because Stalin wanted to start another world war for financial gain. The deal was that Russia would not protect anyone from hitler, and hitler wouldn't try to invade Russia. Since Hitler later would break that pact, many historians like to simply either pretend it never happened, or not tell what the deal really was. See, some people nowadays view Stalin as a hero for his contributions to stopping Hitler - even though Hitler literally could not have successfully started WW2 without Stalin.
The reason I say this, is because technically, if you're going to count deaths caused by Hitler's ideology (which technically would be a fair thing to do), then that same total would be added to Stalin's kill count as well since he egged on the war, which would then put his death count at 70-80 million.
Also, based on numerous autobiographies I've read, being a Christian under Stalin's regime might have been equal to or possibly even worse than being a Jew under Hitler's regime. And nobody can argue Stalin was Christian - he literally died raising his fist at God.
Btw, Hitler being Christian is a misconception which actually was sadly caused by the German church. The church of Germany was so afraid of Hitler that they just folded and did what he wanted and offered him their services, and Hitler then used religious wording when trying to rile them up for his cause (Hitler knew how to file a crowd's spiteful emotions). (Btw, some churches are like this today with modern agendas). Hitler wasn't a Catholic, he simply used the Catholics because they were a large population and he wanted their support. There were legitimate German pastors however - most of them fled the country. One (Deitreich Bonnhafer) famously returned to Germany, and openly spoke against Hitler and actually ended up being involved in a plan to assassinate Hitler, and he felt he had biblical reason to.
