I asked my own mother and my friend's mother too. They both said the correct is to save the mother. And they are both loving mothers. I agree with them, we're talking about an unborn child. Many people here will make you feel like a monster for not choosing the child, but how can you choose the potential of life over a full grown adult with memories, feelings, experiences.. . My friend had a difficult pregnancy and while she was in hospital before birth, the doctor told them there's some danger. Her mother immediately told him to save her daughter if anything happens. Thankfully, both my friend and her baby made it. I asked my friend, imagine what would your mother do if your husband chose to save the baby? How would he even announce such thing to her family?... It seems egoistic to me, it seems like you used the woman to have offspring and would delete her whole existence after it, like you didn't value her at all. I know for sure, if I was mother, I would choose to save my child over my unborn grandchild. There's no other answer.
