If you live in the USA, this has Terri Schiavo-energy all around. It’s different, I know. Terri was alive and braindead. This infant is gonna die. The court is sparing the infant pain.
But why would you keep a child alive to suffer? It’s like Terri in that the parents refuse to think about anyone other than themselves. That’s just cruel / terrible / bad.
These decisions aren’t about the cost of care, they’re about the interests of the individual and, in this case, not prolonging suffering unnecessarily.
