Evil is not unique, but Hitler and his bunch earned their place in history with their mad genocide.  They started before WWII and continued to its final days.  Stalin, our ally, was not an innocent and killed millions.  The 20th century is all of history wrapped in the shiny efficiency of better technology.<p>People will ignore quite a lot that conflicts with their desired perception.  It is amazingly hard for the a being so built to pattern match to break from patterns.  Russia was trading with Germany up until they were attacked.<p>On a personal level, I see celebrities going to places that have awful human rights record then come back to the US and tell us how bad we are.  I have little use for hypocrisy in this life.  Yes, Germany was popular before the war which just means their are plenty of ignorant (both ill-informed and willfully) and useful idiots in the world.
