He gave nice nationalistic speeches and people loved that. But they were also scared as hell of him and his regime.
And that's all well and good, but when it comes down to it, Hitler and his circle were the ones ordering the exterminations. Not the German people.
Hitler personally probably only killed at most 5 people during his dictatorship. The other 6 million Jews were killed by the common German citizen.
Compare how the Italians treated the Jews under the tyrant Mussolini vs. how the Germans treated the Jews under Hitler.
(I am not interested in discussing this further. You can read a book called “Hitler’s Willing Executioners” if the subject interests you.)
