The parents of Terri Schiavo are keeping a body alive like a zombie against the court determined wishes of that woman. They are doing this for themselves because they have deluded themselves that she is "still there". The grotesque horror that they perpetrate on themselves with this delusion and on others should have been stopped years ago.
A series of doctors and tests have determined that the woman's higher brain functions are long dead. The religious based opinion of one who has not been through that examination and thinks that a "feeling" that someone is there is adequate to make a decision on is not to be taken over the carefully determined and court reviewed opinions of those much more knowledgeable about the case.
Mr. Schiavo's motives may well, by this time if not before, be tainted. However, the courts, as I understand it did not relay solely on his say so about Terri Shiavo's wishes. To violate her wishes under these circumstances is to perpertuate a disgusting macabre farce. It is not in the woman's interests, her husbands or the parents (though they are not capable of seeing that) nor is it a good use of scarce medical resourses.
