You've made mention how difficult this scenario is.
There's just no slippery slope that links this case to parents being allowed to essentially murder children under the age of 5, which was what was up for discussion in the other thread.
Think of it like this: the Terri Schiavo didn't lead to some scenario whereby husbands or wives were just outright killing their spouses "just because."
