Your patient "recovered enough to respond to people, eat and he did regain some movement". From what I've read, Terry won't.
I agree with you. I believe that letting her starve is wrong. But there should be some alternative. If her parents wish to keep her alive with feeding, they should be granted that permission.
I also agree with your assessment of her husband. Since he "gave up custody" to the courts, he should have divorced her, especially if he decided to establish a relationship with another woman.
There's no easy answer. I disagree with both extremes... save her at any cost and let her starve. I also think that Congress & Bush made a mistake in passing a bill specifically for one individual.
