Quite an interesting paper you linked:
Conventional wisdom during World War II among German soldiers,
members of the SS and SD as well as police personnel, held that any order given
by a superior officer must be obeyed under any circumstances. Failure to carry
out such an order would result in a threat to life and limb or possibly serious
danger to loved ones. Many students of Nazi history have this same view, even
to this day.
Could a German refuse to participate in the round up and murder of
Jews, gypsies, suspected partisans,”commissars”and Soviet POWs—unarmed
groups of men, women, and children—and survive without getting himself shot
or put into a concentration camp or placing his loved ones in jeopardy?
We may never learn the full answer to this, the ultimate question for
all those placed in such a quandry, because we lack adequate documentation
in many cases to determine the full circumstances and consequences of such a
hazardous risk. There are, however, over 100 cases of individuals whose moral
scruples were weighed in the balance and not found wanting. These individuals
made the choice to refuse participation in the shooting of unarmed civilians or
POWs and none of them paid the ultimate penalty, death! Furthermore,very few
suffered any other serious consequence!
Table of the consequences they faced:
I assumed that there were a large number of unknown cases and that the unknown cases, on average, had less severe consequences. But I haven’t read the paper deeply enough to really know this.
