I agree, but if you treat the mother and labor induces or it causes a miscarriage, that is unintended.
If it is a side-effect. Inducing labor pre-viability (abortion) can't be the solution. But if you are say, giving the mom chemotherapy for acute cancer and it happens to unfortunately induce a miscarriage, that is unintended. But if the solution to the medical problem is to induce a miscarriage (prior to the age of viability, an abortion) that is illicit.
The evil and unintended effect cannot be the direct cause of the good and intended effect:
Rom 3:8 said:
And not rather (as we are slandered, and as some affirm that we say) let us do evil, that there may come good? whose damnation is just.
The crux is, is there any case or said scenario where having to abort at 11 weeks or mom will die at 11 weeks, exists?
That is what was claimed in the Phoenix case. I am not a doctor so I can't tell you the merits of the case, I trust they ascertained the problem and a possible solution (albeit an illicit one) correctly.
The proper way IMO, not being a doctor mind you, is to just go as far as you can where the baby as some kind of chance to survive.
As long as it's post-viability.
How early you push it has to be proportionate to how much there is a danger of losing the mother. If the mother is on her deathbed, yes, you could pull him out at say, 23 or maybe even 22 weeks. But at 11 weeks, it's murder because there is no chance the baby will make it.
You just have to think about it in a non-pregnancy situation. How much risk do you put your children in every day? You drive them in the car -- even though you could crash and you all could die. You let them walk to school -- even though they could get abducted. We judge risks on a daily basis and do what it is we have to do.
On "Good Morning America" yesterday there was a couple who got a speeding ticket rushing to the hospital for their baby to be born. They were going more than 100 miles per hour in a 55 mile per hour zone. So when they got to the hospital, there was an officer waiting there for them. They're fighting the ticket because if he pleads guilty (or is found guilty), he will lose his license for reckless endangerment -- and rightly so! What's the point in putting your life and the lives of your wife and soon-to-be-born son, as well as everyone else on the road, in grave danger just to get to the hospital 5 minutes earlier? That's not proportionate. If he had been going 5 or 10 miles an hour over and an officer stopped him, he probably would have gotten off with a warning to drive more carefully since the officer could see he was rushing to the hospital. That might have been proportionate but 50 miles over is not.
So in the case of the pregnancy, I believe earlier that the Church account inducing labor at 21 weeks or earlier is considered an abortion. Even at 23 weeks, you're only looking at a 20-30% chance of survival. At 24 weeks, there is a 50% chance. In what circumstances would you be willing to put your child in a situation where there is a 90% chance they will die?
Perhaps if you are trapped in a burning building and you throw your child to the streets below in the hopes that someone will catch him -- because if he stays any longer, he will surely die. But you can't throw him because you figure it's better for him to hit the sidewalk than to be burned alive nor could you throw your child out the window if the building is not on fire. You could throw him out the window if it is impossible to both carry him and get out of the building at the same time --
provided there is at least some reasonable chance he might survive.
You could induce pregnancy (throw the child out the window) if there is some reasonable chance the child will survive (i.e. post-viability, at
least 21 weeks) and there is a proportionate reason to do so (the building is on fire and the firemen can't get to you). You can't induce pregnancy in the case of "fetal anomalies incompatible with life" (figuring it's better for him to hit the sidewalk now than to be burned alive later). Nor can you induce, even post-viability, if there is not a grave reason to do so (you can't throw your child out the window if the building is not on fire). You could induce pregnancy if not inducing would lead to the death of the mother (and without a post-/peri-mortem C-section, the death of the child as well) provided that there is a reasonable chance the child will survive.
If this case had taken place when the child was 26 weeks along instead of only 11, inducing labor would have been a licit response but at 11 weeks, it's just murder.
