I think you and I are on the same side -- the person I was answering seemed to think, that just because he wouldn't want to live "like that", Terri shouldn't either.
My point was that he can choose to live a "living will" ( more like a dying will) and leave instructions, but since Terri didn't and there is a great deal of uncertainty, to put it mildly about her wishes, someone else's will should not be imposed upon her -- especially not her "husband's", where more and more evidence is coming to light that he set out to murder her.
Sorry I misunderstood you.
