Q&A: When the mother's life is in danger and both will die, abortion to save the mother is the one exception most pro-lifers accept. Analogous to separating conjoined twins when one is dying — saving one life rather than losing both.

If both mother and child will die without intervention, saving whoever you can is morally justified. This isn't killing to avoid inconvenience — it's triage. Conjoined twins analogy: separating them to save one when the other is dying. Mike doesn't know any pro-lifer who disagrees with this exception.
