Might also be the narcissism of wanting enough time to invest in a child's rearing. Like, in theory, I might have been capable of popping out 3+ kids. Would I have enough time towards invest in all their personhood development needs? Nope, I don't think so. Barely enough time for work and myself. It's kind of why I didn't get a dog. Takes a real asshole to go outside one's species then fail to take care of the doggo. Also real assholes cause a child to be born when the person does not have the stability or desire to do a proper job with a vulnerable little kid.
