Places like Auschwitz became possible due to a sudden and inexplicable boom in morally absent mass murderers in Germany between WW1 and WW2, right?
Or, perhaps, through effective propaganda, groups of people, such as jews and mentally disadvantaged, were painted as "scum"? All it then takes is to find people like you, that
ENJOY seeing "scum get what they deserve".
I have little doubt as to what role you would have taken, were you born in Germany after WW1.
