More total mass murder to his name, exporting evil ideology to a larger part of the world, running a much larger system of concentration camps ... if that's not enough for you, too bad.
"More total mass murder to his name, exporting evil ideology to a larger part of the world, running a much larger system of concentration camps ... if that's not enough for you, too bad."
None of that is logically sufficient because it presupposes that Hitler was stopped, the very point under debate.
Is there anything Stalin did that Hitler wouldn't have done, given sufficient time?
I don't think so, which is why I don't think you can say that Stalin was a "worse monster" than Hitler.
