> The men didn't feel they bore a moral duty to disobey, because these things just had to be done, or so they were told.

That is how they were raised. That kind of thinking was traditional and Nazi school system and propaganda were designed to produce people like that.

It is also not true that anyone would pull the trigger. Even in Germany were many people who having choice participated to the minimum or did not joined groups doing worst things when they could. It is interesting that another popular glib is that "ordinary people who don't fight back are responsible". But people who looked away or were passive should be better off morally then those who could not participate but did (not everyone could avoid such duty).
