People are so naive. After birth abortion happened all the time when the baby was born with holoprosencephaly, where the embryonic forebrain fails to to divide into the hemispheres. resulting in a single-lobed brain structure and severe skull and facial defects, we’re talking unsurvivable (but still born live!) gross anatomical defects.
I will remind you here that humans are biological creatures and , oh there is no God, so just anything can and does go wrong with horrific results. Doctors killed these babies and told the mother it was born dead and the other drs. and nurses involved said nothing. This was considered humane.
So please, this has happened since antiquity and into modern times. Google anencephaly and see what you come up with.
