The starting point is why do humans get violent or cooperate. Because we evolved to seek patterns. THEN you move on to motivations and complexities.
Un, Stalin, and Hitler are monsters. Their motivations aside it came from the cruel side of our species and a sense of selfishness and lust for power. The complexity you might argue is what allowed them to mask their horrors in the guise of justice.
This is why humans stay divided and murder each other. We don't see ourselves as the same species once we start creating these artificial differences and then conflate them to deeply complex excuses and it still amounts to justification to get at power and resources. It is good for that group, but it sucks for global stability.
