Then again, my Oma lived through the period in question, so I know from second-hand some of the psychological trauma that comes with being complicit in that shit.

That trauma seems to get passed down. I didn't truly understand the concept of "Germany's National Shame" until I moved there in the late 80s. It was really hammered home by my schoolmates apologizing for WWII.

They ranged from 15 to 18. Not complicit, but they still felt responsible.
