Hitler's death toll is far larger then Stalins-11 to 17 million in Holocaust alone, add to that 26 million casualties in Soviet Union and 6 milllion in Poland and you already exceed Stalins number of 20 million or so.
And just in
six years. So there is no dispute that Hitler was the bigger killer.
The people who claim "it doesn't matter how you die if you die" are very wrong, that way the massacre of 1,000 Jewish civilians in 1939 Poland by German death squads is lesser evil then death of 4,000 factory workers in Germany 1944 due to Allied bombing. Obviously that is not correct.
Generally what seems to be missing is that Germany led a war to exterminate whole nations based on racist genocidal ideology, around 70100 million Slavs would be eliminated. And we have Roma and Jews as well.
The Soviets fought to control other nations not to exterminate them.
While for example Nazi Germany never accepted Polish state and instead turned occupied territory into one big concentration camp with no education, health facilities and so on, Soviets were willing to create a satellite state, with Polish language, schools, hospitals, transport, Polish factories and labour protection and so on. It's obvious that they were less evil then Nazi Germany and allowed for survival of nations.
The argument about "you had more chance dying in SU then in Nazi Germany" is wrong. In Nazi Germany your chances were based solely on ethnic background. If you were a Jew you had a 99.9 chance of eventually being murdered, while being a German you had a pretty chance of living a good life based on exploitation of other nations.
Nazis would kill a Jewish infant just because he was Jewish infant-in Soviet Union the worst the state would do to you, is to put you into orphanage if your parents were classified as political enemies.
In Nazi Germany if you were a Pole, you considered a creature of lower status then a dog. In Soviet Union you were just a citizen like others, maybe spied more but nobody believed you were an animal for extermination.
The differences that show that the two are not the same in level of killing are obvious-both occupied whole Poland-Nazis killed 6 million Polish citizens, while Soviet made casualties are around 300-400,000.
The Soviets imposed a brutal regime on their own people that killed millions following lunatic and untenable sociopolitical theories, picking victims among scapegoat social classes, national minorities, everyone that could be remotely suspected of harboring a bad opinion of the regime, and at good amount of random victims picked to terrorize the others into abject obedience. The Nazis pretty much left the bulk of their own people alone, if in a brutal police state, and killed millions following lunatic and untenable racial theories, picking victims among scapegoats minorities and foreign nationalities, part in order to wipe them our for their loony colonization projects, part in order to terrorize the others into abject obedience
You forgot about the whole "let's kill all the Jews and 70 to 100 million Slavs, because they are untermensch creatures" thing in Nazi Germany
And the claim "The Nazis pretty much left the bulk of their own people alone" is clear revisionism. Most of the people under Nazi rule were opressed as untermenschen, unless you are trying to claim Nazi occupied Poland, Russia, Ukraine, was not under their rule but somebody's else.
As a Pole I would never want to live under Nazi rule, hunted down as subhuman. I lived under Soviet rule, and I don't recall being treated in racist way, being sent to concentration camp, or my whole family murdered. Sure there was propaganda, poverty and economic corruption, but it preferable to death from the Nazis.
