No one knows what really goes on when the soul leaves the conscious mind or the conscious mind cannot communicate. In any case, Terri has shown signs of wanting to live. She has moaned and tried to fight for her right to stay here on earth.
I do not claim to know what is right and wrong here. I imagine the medical bills cost alot of money. However, someone mentioned that her husband wanted to re-marry and maybe it would be easier this way. I am not sure if that is a valid point or not. I do not know all the details.
I am just praying for a miracle and for the whole Shiavo family. If she has kids, I am sure they want their Mom to have a chance at life.
