Bigger issue with Stalin in the U.K. is that - despite the Cold War swing against Communism - he was Uncle Joe. He was on our side, he was one of the Goid Guys. So he needs to Stay Good. The narrative needs to be simple We Were The Good Guys And The Germans Were The Bad Guys - frequently not even making the distinction between "Germans" & "Nazis". There was a certain amount of suppression of information about the exact extent of the atrocities he carried out, of course, but post-Glasnost there really is no excuse...
Again, with Mao, he had a touch of the folk hero - and the Chinese were The Good Guys, fighting the Japanese. Even more secrecy. Definitely a lot of Othering at play there though.
I'm not sure about the "people like us" - at the time Jews were still othered & now would you see citizens of the USSR as so much further removed? I think there's a lot of collective [inherited] guilt, more than anything, though, in a way there isn't with Mao or Stalin - the feeling that We Should Have Done Something To Prevent It. It's the British version of what drove my Daddy's roommate on his year abroad to apologise to him for the war, but including saying "you know, Name, those things that happened during the war... they had nothing to do with me". Well clearly not, given he was born well after it. But that need to make it clear he had no personal responsibility while still carrying a heavy load of guilt for it... oof.
