The OP discusses instances where individual Germans refused to follow orders. One example:
> By his action to obtain this order, Griese refused the request of the SD to have his men participate in the execution of Jews in his area.
>In fact, the SD had shot the 365 Jews themselves while he was on his journey to and from Konigsberg
Nazi leadership recognized that mass execution of Jews (and others) by firearm was taking a psychological toll on the Germans being ordered to do so, which is one of the reasons that more abstract, industrial methods (e.g. gas chambers) were developed.
I draw attention to the parent's false equivalency of Nazi Germany and 21st Century USA. I describe the Nazi regime's recognition of the morale toll on its soldiers of gunning down innocent souls. Himmler himself saw this as an "issue."
Conjecture basis the article that the Nazi German legal system is similar to the modern American system is logically fallacious and dangerous insofar as it suggests that Nazism is compatible with contemporary American political and ethical values.
