Alive or Dead, Terri Schiavo?

Terri Schiavo, now 41, suffered in 1992 from what they believe was an unbalanced amount of potassium in her body. This caused a lack of oxygen flow to her brain for only about five minutes. However, now she is near brain dead because of this. When this occurred, her husband at the time was supposedly reported her legal guardian. He as her husband and legal guardian wants her dead out of 'mercy'. In 2000 he went to court with a successful petition to have her feeding tube removed, which afterwards was re-inserted. This was due to the passing of 'Terri's Law' which gave Jeb Bush, Florida's governor, the power to decide. This in 2004, however, is viewed as unconstitutional and so is overturned. Now the current issue is that her feeding tube has been removed since last friday and she will likely not have it re-inserted again and so die very soon. Her family has tried appeals to this, but so far has had no luck. So my question is, should she die for not knowing anything and being brain dead, or should she be kept alive for the hope that she may, without being able to express it, wants to be alive.
