Morphine is given to all patients removed from feeding tubes, whether they have cognitive abilities or not.
It's called a "just in case" measure.
That's basically what I said in my first post to you. If doctors were certain about her level of awareness there would be no need to give her morphine. Because they are not certain, as I said before, I don't think it's unreasonable to assume that she might have had some awareness of the pain of the dehydration/starvation process. I say "had" now because she is dead.
