Yeah.... Winston Churchill's initiatives killed plenty of Europeans. The main reason Hitler is demonized is because he lost the war, that's how history works.
And to be fair the main reason why Rhoades and especially Leopold aren't on the same level as Hitler is because most people don't really study history. I don't think I've ever seen anyone claim Leopold was a good dude, he was ostracized in his own lifetime once his crimes were made public.
