By and far the scariest thing about Hitler’s rise to power is not the small minority of true believers, but rather the large masses of the population that weren’t true believers but went along with it for one reason or another. Perhaps they wanted career advancement, perhaps they feared communists and trade unionists more, or maybe they thought they could do more good on the inside. Whatever the personal reason, tons and tons of perfectly reasonable, nice Germans voted for, joined, or stood by as the Nazis took power and plunged the world into war and committed mass murder.
