The Terri Schiavo dilemma

I'm sure by now everyone is familiar with the Terri Schiavo case.
A woman having been in a vegetative state for 15 years, awake but not aware the doctors say. According to her husband her living will was to end an existence as such. He has gone through 19 courts over the years, all of which gave him right. Terri Schiavo's parents are fighting the Supreme Court's decision of disconnecting the tubes... or actually, they have been disconnected and they want them reconnected.

Anyway, what this case made me ponder are two things:
1. Are there actually people who would like to continue their life tied to a bed not being able to move anything at all, being kept alive artificially? And what about a case like this? According to the story Terri Schiavo doesn't even know she is alive. Would anyone want to live such an existence...if they knew beforehand it's coming? I certainly wouldn't want to burden my family with such pain and cost..

2. And this one is a really tough one for me. So, ... if you believe in God you know that suicide is apparently unacceptable (throwing away gift of God and plan or something like that). Murder isn't very much the thing to do either... except when at war, if I'm correct.
So, what does a case like this fall into? Is it suicide, murder, or is it an acceptable death, for she wouldn't live without the medical assistance anyway?
