A baby can die after birth. It can die before its first breath, or be still-born.
I disagree that preventing abortion equates to saving its life.
Indeed, it may live a short life filled with suffering, but the statement in the OP is beyond facile.
It's not a baby until it is born, it remains insentient in the womb, so it cannot experience emotional pain, the neural connections to the developing brain don't start to develop before 24 weeks, so it cannot suffer physical pain, unlike the woman whose body it is a part of for most of its development.
The OP also completely ignores the suffering of any woman whose bodily autonomy is forcibly taken away, and focus entirely on the insentient balstocyst they think should have more rights than the woman it is developing in. I could go on of course, but this will do for now, at least it sets the argument on a more even footing, than the facile false dichotomy of the yes / no in the OP.
