There's a point where you've got to admit that someone can't look after themselves regardless of the injustices that may have led them to that point. I think the lady in this story has reached the limit.
Maybe if the lady had intervention and better support early on then she might have had a fighting chance. Maybe not- maybe her problems were such that she was unfortunately doomed anyway. Regardless she clearly can't look after herself and the point of softly softly community health support has passed. IMO forced sterilisation or committal to a mental institution where she will have access to 24/7 care and treatment is the only thing that will protect her future children and herself. Being a fan of committal doesn't mean I don't value human life, it just means I am being realistic.
