Exactly. It's a pretty small number of people who are this terrible. Thinking of it in evolutionary terms creates a sense of fatalism. If you look globally since the invention of agriculture, it's very clear that a) humans are extremely flexible, and b) culture matters hugely to how societies turn out.

Culture is something we inherit, but it's something we can change. If we want things to be less fucked up for the next generation, we can do that. As many before us have.
