Let's say -- for the sake of discussion -- that her husband did have some sense of her wishes. Let me ask a few follow-ups then:
You would not deny, would you, that her siblings and parents and friends would not also have some sense of her wishes?
You would not deny, would you, that her parents and siblings have some very reasonable claim as parties in the consideration of something as irretrivably final as death?
You would not deny, would you, that while her husband may have had and so expressed an honest sense of what he perceived to be her wishes, that such a "sense" is not perfect, it is a poorer grade of proof, than say an unequivocally clear and repeated expression by Terri of that wish, or better of a properly signed and witnessed living will?
