You can’t really compare horrors like those which followed those men. There also isn’t any justifiable reason to- by the human ideas of justice, either man deserves the most severe punishment and recrimination in name for themselves and their regimes and ideals which we can apply. For all time and throughout the world both names should be synonymous with horrors and twisted pervasive philosophies.
The only reason to compare how much “worse” one person on this level of vileness is than the other, is if one is attempting to make one of these men look better than history remembers them. To get people to start to think: “well actually, this guy wasn’t too bad..” “well actually, he did have some good points and not all his deeds or ideas were twisted and wrong…” To open a door through which one of them can find some redemption and perhaps even acceptance or even reverence through revisionist history.
In not too long here WW2 will have started 100 years ago, shortly after it will have ended 100 years ago and children will be born into a world where WW2 is as far away for them as the civil war was for many of your parents or grandparents or even great grand parents. Already most people who were there are dead, and it won’t be too much longer until the people who were able to talk to that first generation and get first hand accounts are gone. Many today already forget or don’t believe, revise or disassociate from the truth or full impact of that period in history. It’s just a story about a world that is too far in time and detail for them to truly relate to. Hitler, Stalin, Mao, Pol Pot, etc. we don’t need to rank them. The horrors on their names defy ranking and they surpass the point where any virtues or good associated with them can redeem them or wash away their filth. No one lived through each and all of their horrors, so no one can say “eh, I didn’t mind this one as much…”
