I agree w/ degsme. I would also like to point out the purpose of hypotheticals is not to reflect a completely likely scenario, but to fulfill a logical purpose, which is to disprove absolutes.
For instance, can you think of a scenario, as degme has been trying to do, in which an ob-gyn would have to make that choice (again, the scenario doesn't have to be likely or have a high statistic of probability) in which the doctor would have to choose between his/her moral convictions against abortions and his/her duty to help the health of the mother?
Hypo: A woman is 6 months pregnant and was in a very serious car accident. The woman is rushed to the hospital and it is diagnosed that the woman is close to death, but her baby is fine. Upon further tests they discover the baby is putting so much strain on the woman and any attempts to deliver her fetus/baby will cause them both to die. If the fetus stays in, however, this too will cause her death. The only way save the woman is to preform an abortion on her. The only doctor available to do this procedure has a moral objection to abortions, but if he/she cannot do this proceedure, the patient would surely die.
So, what would you suggest the doctor to do?
