"I was just following orders," is a bit of a meme, but it's also true, and even more so in the context of Prussian-style military discipline. Disobeying an order was not an option. You carry it out no matter what, but the responsibility lies with the commander. It gets more murky for the civilians who theoretically could have walked away, but a lot of them had a similar mindset that they were just doing their jobs. And you have to keep in mind that all of the Nazi's racial ideology had been codified into law at the time. So you were once again just implementing the rules, even if those rules were actually harmful.

But what this episode also highlights is the opposite of this in the form of the American approach that is much more flexible and willing to bend the rules if necessary. Rightfully, the Allies could and probably should have brought everyone to justice, but they realised that a lot of the Nazi scientists were extremely valuable assets that they needed to get a leg up on the Soviets. So rather than execute them or put them in prison and throw away the key, they recruited them.

That's kind of interesting, though considering that the German army (and presumably Prussian before that?) was know for giving a relatively huge amount of leeway and authority to more junior officers.

Supposedly while the French and British officers were frozen waiting for new orders to be telegraphed when something didn't go according to plan, Germans took the initiative based on what's happening on the ground. US and other countries adopted this doctrine after the war because of how unexpected successful the German army was (despite being outgunned by the French and the soviets who had better tanks and more trucks just couldn't figure out how to use them efficiently)
