I've thought about situations like this. I don't think it is proper to label her as "right" or "wrong" in this situation. When you're playing with odds upon which people's lives depend, how CAN you make a proper judgment? If it was known for sure that all the babies would die, you'd have to choose to abort some to save the rest. If it was known for sure that they would all survive, you'd have to choose to have them all. But it was not known ahead of time, nor was there enough certainty that any possible outcome would be considered an unexpected turn of events. The decision was between her and God, and she had to make that decision in whatever way was most bearable to her conscience.

Those who are calling her "wrong" (or "stupid") are judging too harshly, and doing so from a state of emotional comfort that is absolutely ignorant of the great complexity of distress that is bound to have plagued her. ("Not the decision I would have made" is obviously an ok response. It's also one I dare not make on my own, though, because I don't know that I could predict how I would feel in such a situation, and I'd be trusting in God to lead me one way or the other, and I wouldn't know that until it happened.)

My heart breaks for her.
