They will start killing the newborns born with a congenital problem before the parents even see them. They probably do this already. My step-daughter wouldn’t have had a chance (heart chamber). Obstetric wards will have their own in-department death panels.
The only time my father came close to killing someone was at the birth of my sister's first child. The doctor arrived drunk and the hospital failed to stop him from carrying out the Cesarean procedure. My sister nearly died. The child did, though. I honestly think that if she had also died, I would have grown up without a Dad.
