Do u guys know abt the woman who's like brain dead but still has to have a baby??

It's like so fucking inhumane and every tiktok I see abt it, the comments are always filled with like "I would be happy to be that woman." well ur body ur choice but damn... She's not even alive. She's just a vessel. That's not humane. There's literally a high chance the baby ends up dying or body not okay to function. I don't understand why is this allowed and how pro-life thinks it's okay...
