there's no such thing as entirely someone's fault. you live in black and white.
i don't know, was the whole germany literal nazi? well, half europe was. was hitler the enemy of the whole world? well, not until he did his job keeping commies under control. noone cared about jews and racism, ok? einstein moved to us from nazi germany and was shocked by racism towards black. he was lucky he's not black.
it's not a tale of good and bad. and it doesn't need to. hating your enemy is hating yourself for the enemy being in your mind, being close to you, being in your news or the same continent. love your enemy to love yourself.
