Actually, I wouldn’t have obeyed. I always was stubborn and pigheaded, which of course got me into a lot of trouble...
The whole premise of this article is a steaming pile of bull, and these experiments have effectively nothing to do with the vicious savagery of the Nazi regime.
It’s been well-documented that there was no pressure to be involved in the killing operations, and indeed any soldier who requested reassignment were readily granted that request, even if it was just because they got queasy at the sight of blood and brains as opposed to any kind of moral principle. The Einsatzgruppen were volunteer squads.
Likewise, a theory of social or authoritarian coercion cannot explain the zeal and vigor with which most of the killers pursued and carried out their duties. Ghetto liquidators were meticulous and thorough, even though they could have simply refrained from applying stethoscopes to walls and ceilings in their search for Jews to murder. A German soldier could simply shoot a Jewish child, rather than grabbing her by the hair, dangling her from his fist for a moment, and then shooting her, but he didn’t. And even as the German army was falling apart at the seams, there was a frenzied effort to continue killing Jews at all costs - even at the cost of military effectiveness.
The Nazi brutality stemmed not from coercion of unwilling participants, but the societal cultivation of willing participants over the course of decades, or centuries, worth of incitement - the same kind of incitement you’re seeing today in leftist cities outside Israeli consulates.
