Wournos Didn't Suffer, Why Should Schiavo?

Not too long ago, a Florida court decided that Aileen Wournos should die after being convicted of committing multiple murders. Consequently, she was given a lethal injection and she quickly, painlessly expired.

Quite recently, a Florida court decided that Terry Schiavo should die because doctors believe she is in a persistent vegetative state. Consequently, she is going to be slowly, painfully starved to death.

If Terry Schiavo is to be killed, why should she have to suffer? Aileen Wournos didn't.
