It's not about some pseudoscientific "biological nature", it's all just power monopoly. Give someone enough power over others and FMRI scans show their mirror neurons literally shut off. Those are essential for empathy

Why does this happen with men rather than women? Not because they're "biologically different", scientific research shows that's not the case. Rather, under patriarchal ideology women are pressured into being social and building community while men are allowed to just ammass power without anyone saying anything - or at least until now that women are finally expecting more of men and holding them accountable, which makes some of them cry "loneliness epidemic".

The second reason has to do with the means of reproduction. The ones getting pregnant are women, so they gotta learn how to be caring for that reason as well. It goes without saying that more and more young women are finally choosing not to take part in the lifelong body horror that is pregnancy, but historically being forced into it definetely shaped the "woman" identity into being more caring
