Another note on the original post, their argument could also be used to justify going through the NICU and killing every newborn. So there's a clear 'pro life' bias going on here, with acts that bring more life being seen as good, regardless of consent. Wouldn't a more reasoned approach be to maintain, keep those who are alive, alive, and those not yet existing, unexisting? Forcing a being across the border is bad, regardless of direction.
