Thank you for recommending this movie.
Muntze is such a knight, he follows a fundermental rule of a man to help the innocent woman ignoring the racism, he insist on his justice as a man fight against the despicable murder of Jewish riches,he has a pristine human principle that is not shaked by Hitler's racism spam, he pays his life for the kindness and justice as a man.
Hans is another kind of man, he lost his fundermental justice, he put everything include his passion as a pawn to fit the bill of his avaricious.
Ellis as a such a fragile victim, she can't differentiate the two different kind of man, even not me, as an on-looker.
actually, the story is about the traitor and how to kill the traitor, but the director is good, the plot is tight, and the rendition is well-organized in a logical way..

I think Nazi may feel Muntze as a traitor, since he want to negotiate with the resistant organization, thus to compromise and avoid more blood shed, Nazi might feel it was his compromise that leads to their final defeat..
