I think you may be right - she may have been worse off than anyone believed, but they still did not confirm PVS as he said it was a clinical, not a pathological diagnosis, so to me, it is still an unsettled issue.
But regardless of the PVS issue, it just was not right for this woman to die the way she did when she had loving family members who would have taken care of her. I still feel that way - it was just not right. Maybe being disabled myself, it is even more upsetting.
You can discuss whether it's right or wrong for a family to decide to remove a feeding tube without calling the person you agree with a murderer.
