Maladaptive in evolution means that however those maladaptive people behave, whether hostile men or women who don't care about having babies, well, those people's genes will gradually die out, and whatever maladaptive behaviors cause them to have fewer children will contribute to them dying out and not passing those behaviors on to future generations. Only reasonable men and women who want to have families will remain into future generations. Just give it time. If you choose not to have children, your kind will die out: https://medium.com/non-violence/stakeholder-control-deliberately-childless-adults-impoverish-everyone-need-global-poor-to-remain-a0e98126c133
