I don’t know if this is true, but I’ve heard that when the Nazis were having soldiers round up and shoot people (before the Holocaust became more industrial and systematic), as part of the preparation for having them execute civilians, the Nazi officers explicitly offered their soldiers the chance to excuse themselves (on an individual basis) from having to actually perform the executions themselves with no further consequences.
