what about all the people who wish they were never born, or otherwise contribute nothing to society.i'm not a eugenicist but a giant black woman lubed up in chicken grease shitting out her seventh baby for SSI money or a 12 year old girl who's gonna have incest kids. the probability of someone being worth something to someone not being worth anything is probably like 1:10. the people who are worth something are less likely to ever require that anyway, and if they do it's not generally because "lol lets kill sum babies", there are times where it is objectively better not only for the parents, society, but also for themselves to not have to bare through a tortured existence.
realistically, if you don't let an african baby grow up eating out of a garbage can while his mother blows cigarette smoke in his face and dissects his teddy bears if he doesnt go to bedbefore 3 AM, you're prolly doing it a favor.
