some historians estimated that the numbers killed by Stalin's regime were 20 million or higher. (Same link as before: https://en.m.wikipedia.org/wiki/Excess_mortality_in_the_Soviet_Union_under_Joseph_Stalin)

It's more that a million.

I don't know why you made this discussion about if he was as bad as Hitler. I never said so. I'm just saying that those numbers are not that far apart from each other. Thus making Stalin a murderer of millions. This discussion originated in a guy basicly saying that Stalin was indeed a great leader and personality. Which he is not.

And he willingly allied with Hitler. So moral he was OK with the crimes Hitler committed. At the same Time he deported a lot of people himself. Not as many and not as organized as Hitler, but still in the millions.

Stalin was a bad guy and Hitler was way worse. Happy? Just because that other guy was worse they can still play in the same category. "People who killed millions and deported a lot of people"
