It isn't. There was no way of knowing ahead of time the baby could be carried to full term, and that early in the process the chances of spontaneous abortion are still high. A month. That's early. "Strong will to live" doesn't enter into it at four weeks. If both baby and mother had died, what would that have served?
It's wrong to pretend this isn't a difficult one.
...but she gave her life to give him every opportunity to get there.
She chose life.
I think you just don't get it.
There would be no "have to think about it" for me. To voluntarily abort a baby is to commit murder. I couldn't do it.
It's true there was no way of knowing if the baby would have aborted early or not. However, if it had aborted naturally she could have then received treatment. But as long as the baby was alive and growing, this true Mother who truly lived up to the name of "Mother" (unlike so many women of today), did what was right: she left the decision for life and death in God's hands, rather than taking it into her own. He could have preserved her life also, or caused the baby to abort naturally, but He didn't.
If both had died, what would it have served? That's not for us to answer. It is ours to be obedient to Him and leave the consequences to Him, whatever they may be. Death sometimes serves His purpsoes more than life does, especially when we realize that physical death is not the end of one's life.
