I think that technically they were? But obviously not all followed Riddler's ideology.
From what i've heard and read about all these years, i'm talking mostly about the Wehrmacht. If I remember correctly, almost none of them were told about the mass killings of the innocent jewish people, and basically all they mainly did were follow orders and do what they were told to do. (In the name of honor, or however you call it.) Obviously, like you said, not all of them followed Riddler's ideology, and all of the ACTUAL national socialist members stayed in Berlin/areas around Berlin and paraded around. I've heard the SS (Schutzstaffel) were actually more crueler than the Wehrmacht, and another difference from the SS was that they were under command by Heinrich Himmler. Until 1945 I heard that the national socialists did try to fight against Russian troops whenever they stormed into Berlin.
Just saying, not all of that may be true. It's mainly based on what i've read/heard in the past years.
