It's got nothing to do with there being a live baby at the end of it. It's to do with forcing life changing and traumatic medical procedures on someone.
No, it has to with making medical decisions for someone who does not have capacity to make medical decisions for themselves. This happens ALL the time, only difference is there is a fetus involved here. It happens for children, it happens for vulnerable adults, it happens for people who have dementia.
How would you feel if the ruling was about an organ transplant? Potentially life saving, but also puts that person forever dependent on medication and at higher risk of infection. Or a risky brain surgery? Could help them, but also could kill them.
How is her life more changed by not having a baby now and ending a pregnancy, than by continuing a pregnancy, having a baby, having the baby taken away, or having to move into residential care?
What if she carried through the pregnancy and the decision was she needed a c-section but she refused as it was not “her wishes”? If she didn’t do it, her baby would die, and she would likely also die. Would you feel okay about a “traumatic medical procedure” being forced then?
