A person has as much right to a dignified death as a life. If you take
that away from them for to pander to the religious right in (as the
government attempted to do in the case of
Mrs
Schiavo) then there is a serious chance of prolonging human
misery. I know that this particular case was not black and white, and
there have been claims that the husband wanted to hasten her death (and
even claiming that he strangled her when she collapsed).
I believe in all cases where a person is in left a state like Mrs
Schiavo with no signs of improvement should be taken off all life
support after one year (or whatever the maximum length of time the law
can charge someone of murder following death from an assault).
There is noone in my family that would want to be kept on a life
support machine if they were reduced to that level (myself included)
and I would let no government on earth stop them from dying with
dignity.
If you consider the advances of medical science, in a few years
existing as a brain in a jam jar like in b-movies might be possible,
and there is no way I would have that happen to me, or anyone else I
care for. I'm surprised they aren't lobbying to have people exhumed
from their graves and resusicated.
