The Einsatzgruppen, and other kill squads, were purely voluntary affairs. Not sure about "local" guards, maybe some of those were drafted. Nobody of these guys can hide behind "we just followed orders". It is just sad that the little guys, like a secretary and lowly prison guard, are prosecuted now, when a lot of the mid-level organizers, incl. Doctors and officers in charge, were left alone in Western Germany while they were still alive.

EDIT: You didn't have a choice going to war (talking about the male population), you had a choice in volunteering for counter partisan warfare, Einsatzgruppen, concentration camp duty,... And that choice is the crucial one here.
