This is yet another example of why I’m an anti-theist. Only through generations of telling people that they are “god’s chosen people” can you obtain this level of revolting dehumanization.
Only through ritualistic indoctrination can you achieve this level of psychopathy in an otherwise normal human.
(And yes, I know that sociopaths and psychopaths exist, but they aren’t a recognized homogeneous organization with a consolidated and specific, rigid belief system.)
