@juglugs I also read Hannah Arendt's Eichmann in Jerusalem. The subtitle is very apt: On the Banality of Evil. She made the point that it wasn't just the handful of monsters and sociopaths at the top, but rather a mass of ordinary, average Germans who enabled and empowered the actions of the state by simply "following orders."
That postwar excuse was recently used by defendants in the trials of the Jan. 6 insurrectionists.
