The Nazi Officer was true to his as well. In fact, he stood up quite well for his "principles".
Its not enough to stand up for your principles. It also matters what they are.
I thought this movie addressed the fundamental principles of the conflict, that were neither birthed or died with the Nazi era. Rather, those principles were around at least since the Jacobins, and are healthily thriving to this day.
The movie was well-made, both in their discussion over whose life was worth living, who had the right to make the judgment of Death, and most of all...in the symbolic treatment of light.
What did everyone else think of how he shuts the window curtains and turns on an electric light, and Sophie tilts her face up toward's the sun?
