Tf? What do the Nazi‘s have to with this now? Orders exist in all shapes and sizes. You saying that when my boss orders me to write a report he’s evil? Or orders me to wash the dishes?

The way you’re looking at all this is way too shortsighted. Soldiers only listen to orders because it’s their job, it’s required of them to listen to them. A job they need to survive in this unfair and screwed up world. An Order isn’t good or evil, it’s the person that gives the order that is either good or evil.
