Terri Schiavo, what an unfortunate case. Seems like this is what everyone's been talking about lately. So here are my views on the matter:
Terri's cerebral cortex, according to experts, is completely gone. That along with cognition, sense of self, consciousness, feeling pain, and really everything which makes us human. "Terri" died years ago. What makes a person is not their body. A man who lost an arm is not less of a person. Personhood sits in the brain, specifically the cortex. When the cortex is gone, all you have left is a shell. So the question of morality if it's right to kill her is moot. She's already dead.
Second, according to the courts, it has been made clear to them that Terri would want to die if she was ever in such a condition. I'm no expert here and I don't know what she might have wanted or might not have wanted. I don't know her or any of the people involved. This is what the courts found and if true then Terri's wishes should be followed through.
This is what the courts do, they are fact finders. They're not infallible but I have no status to go on second-guessing their rulings. So, like I said, if Terri would have wanted to die, so be it.
The only final issue really is the method of death. Had Terri been on a machine and the question was about whether to pull the plug, that's one thing. She'd be dead in minutes and that would be that. But she only needs a simple feeding tube to keep her body alive. Dehydration and starvation are nasty ways to die and I think that's what really bothers a lot of people.
I think it's silly that legally they can order her to starve to death, but they can't order an overdose of morphine or other poison to kill her quickly. Terri can't tell the difference and I think that would make a lot of people feel better.
