If the soldiers had to die, why wouldn’t Jews have to die too? It's as simple as that. As soon as we recognize that Germany was killing its own soldiers, everything falls into place.

Hitler was replicating what already had occurred in the First World War, with Jews in death camps substituting for soldiers on the field of battle.

The requirement that Jews be absolutely obedient replicated the absolute obedience of the soldier: a negative version of "sacrifice" for the state. 

War = good death (sacrifice/dying for Germany).

The Holocaust = bad death (Holocaust = burnt offering, sacrifice, dying for Germany).

But a dead body is a dead body, no matter how we label the dead body. We don't want to say this. We want to continue to "glorify" the soldier's dead body, even as we pity the dead body of a Jew.

Pity the dead body of the soldier. This is psychic progress. An advance in thinking. Moving toward the truth. Not easy to make this shift in consciousness, but very worthwhile.
