It is about spirituality.
Do you believe in God and Heaven?
Do you personally think that she will go to Hell, and that is why you are fighting so hard to keep her body alive? By keeping the body alive, she will not go to Hell?
If so, then I can understand why you and others are fighting so hard to keep her body alive.
Either you are a genuine Heretic (of the 'Soul-good/Body-bad') variety, or you have lost your mental faculties.
Either choice is not good...
