Hmmm, if she's enduring suffering, that would indicate she has feelings. If she has feelings she must be aware in some capacity. If she's aware in some capacity she must not be in a vegatative state or a vegetable. If she's not a vegetable then the whole argument for her death no longer applies.
Can't have it both ways.
No, it is a recognition of the Christian belief that Terri will be whole again when she is with God.
