Abortion poses risks to the mother psychological and physical.
While there’s some mental risk to the mother related to carrying a baby. Ultimately, you can give it up for adoption. I haven’t seen studies on the exact damage carrying a baby to term is, but I expect it’s relatively low when compared to abortion. That said, I think we should follow the evidence.
Luckily, those cases are extremely rare. Further, the question is still when do you take the life of the human the woman is carrying? I think that’s a complex issue, as even if someone was born of rape or incest, we don’t discuss killing them at 1yr old.
