The only way I could rationalize the OG Nazis...trying to get into their head and how they managed to do the things they did...was that they were straight up brainwashed.
It sounded crazy when I was younger. Like, something out of a comic book instead of a history book.
But as I watch and try to critically understand how the modern propaganda machine works, I can't help but wonder if maybe I was right.
OG Nazis experienced the same thing. Killing people on en masse mentally fucks with your head, even if the individuals you kill are perceived as vermin/degenerates. This is why they moved on to using other means that is more dehumanizing i.e. pressing a button for the gas chamber
Not sure if "OG Nazis" only include the first generation, but their Children were pretty much brainwashed.
You can look up "Hitler Jugend" If you want, that organisation basically indoctrinated children while growing up. Right when humans are the easiest to manipulate.
