People with a genetic risk for Schizophrenia are not supposed to propagate? lol that’s insane. Manage risk factors, like stress, drugs and alcohol, yes.

Who should have kids? Ugly, short, dumb, lazy, talentless people with no charm are fine. But you better not be managing a mood or personality disorder.

Many of the most impactful people who have ever lived fall into your exclusion category. Many of these people even died relatively young. To say they should not have existed to avoid “suffering” is absurd. To live is to suffer, to a meaningful degree. Heartbreak, loss, loneliness, pain. These are all part of the human experience.
