Here's the creepy fact of the day:

"Throughout the course of the litigation, deposition and trial testimony by members of the Schindler family voiced the disturbing belief that they would keep Theresa alive at any and all costs. Nearly gruesome examples were given, eliciting agreement by family members that in the event Theresa should contract diabetes and subsequent gangrene in each of her limbs, they would agree to amputate each limb, and would then, were she to be diagnosed with heart disease, perform open heart surgery. There was additional, difficult testimony that appeared to establish that despite the sad and undesirable condition of Theresa, the parents still derived joy from having her alive, even if Theresa might not be at all aware of her environment given the persistent vegetative state. Within the testimony, as part of the hypotheticals presented, Schindler family members stated that even if Theresa had told them of her intention to have artificial nutrition withdrawn, they would not do it. Throughout this painful and difficult trial, the family acknowledged that Theresa was in a diagnosed persistent vegetative state. "

Sorry, and with all due respect to grieving parents, but that's borderline abuse, and certainly selfish. From this, you can see that, according to the Schilndlers at least, this was not about Terry's wishes.
