Ah, so who is going to force the C-section/normal birth to happen? The authorities, with guns? If that scene is ok with someone, that's where I'd disagree with them, because it's clearly cruel.
There's countless situations where I could judge someone's behavior as a thing they should never do, even though I'm not in their shoes, but this isn't one of them. If a mother wants to abort, that's just on her! Maybe the suffering of the fetus is tragic, but it's all her choice and I can't really judge her because I'm not her. I accept I can't prevent every bad or possibly bad outcome and end all suffering.
Edit: I appreciate dialog on the specifics of these things. I think people just... assume that because they're all on the same "side" they come to the same beliefs and conclusions from the same reasoning (or that everyone around them has a reasoning to begin with) and that can end up causing huge problems.
