Re: An even darker view:
It'd be too easy to blame the failings of humans on determinism, whether biological or mystical. Humans are entirely responsible for their fuck-ups.
I'll give you the "one hell of a coincidence" on misogyny, but racism and war seem par for the course given human greed and egotism. If you want to get people to help you get other people's wealth, you're going to have to give them reasons. Say 'they eat babies!' or 'they don't look like us so they're not human so they don't count', and voila.
