Interesting, but following the logic of that article, then every German officer would be guilty of perpetrating the holocaust, or at least being an accessory to it. I personally don't agree with that premise. I find it difficult to believe that all German officers were fully aware of what was going on. Sure, there were some that were, but certainly not all of them.
Besides, as a soldier, you are a soldier first and foremost. If your objective is to take the land, that is your job. What happens in those lands after you have taken them is not necessarily within your control.
