That tattoo you think says "Hope"? It means "a period of time."
Last night I finally watched Blind Spot: Hitler's Secretary, a film of interviews in 2001 with Traudl Junge, who lived in his bunkers, took dictation from and ate meals with Hitler, and was present during his last week in Berlin.
He never had any sense that he was a criminal destroying a nation, he thought he was pursuing lofty ideals.
And I think it's also the case that if you value and respect someone you don't really want to destroy the image of that person...you don't want to know, in fact if disaster lies beyond the facade.
