About Napoleon, he brought a law code that gave most of Europe its first dose of true rights ever, he was considered a villian by the old gaurd monachys that feared the revolutionary ideals of France.
Hitler was a mass murderer that slaughtered his own people as well as many others, he will never be considered anything but scum, and rightfully so.
There were some in West Germany who, even after the war, still had good things to say about him. In East Germany, Hoenecker probably shot anyone who said such a thing.
Not likely.
East Germany handled their Nazis the same way West Germany did, and the US liked them some nazis too.
Their "expertise" helped setting up the NVA and the Stasi, e.g. all the while the East German anti-fascist heroes were pointing fingers at West Germany for doing the same. Well not quite the same. No totalitarian regime was installed in West Germany. oops.
