I understand where the OP is coming from. My ex and I discussed not having kids because of problems we had. Among them: depression, anxiety, epilepsy, blood clotting disorder (leading to multiple pulmonary embolisms), alcoholism, and many cancers. Do I really want to subject a child to that?!

Look, we have solidly rejected eugenics since the middle of the 20th century.
We also creep back up close to that with our fascination with "positive eugenics" in the form of "designer babies."
We rant and blame the folks who have too many kids, mildly bad kids who don't dutifully contribute to the GDP and lose our minds about the serial killers when they appear.
We also withdraw support in the form of well-funded education, health-care and the rest.
And so, friends, we have painted ourselves into quite a corner. And we collectively did this, only to leave a few on the suffering margins-- the people who have bad lives to carry on with not so much as our sympathy. It must be that each of us is banking on not being *that* person who bears the weight of everyone else's rather vague and uninformed ideas.
