re: When did the German soldiers of WWII realize they were the 'bad guys'?

Sorry. Did not read all that comes before the original post and I am sure that someone has pointed out the fact that German soldiers were either killing or witnessing the killing of innocent, unarmed noncombatants {many of whom were Jews) in the East in the late summer and early fall of 1941. Most of those men were Christians and although most had also been indoctrinated with much of Nazi ideaology, a great number were repelled by what they saw. So, in essence and in answer to the original post, many German soldiers realized they were the "bad guys" as early as several months after the invasion of Russia. Then, again, they were just excitable boys.
