This is not directed at any poster, just thought I should also highlight the fact not all people who identify as Christians are opposed to euthanasia.
Anecdotal; my family (immediate and extended) are what I would term conservative Christians. No drinking, swearing, sex before marriage, or any of that other fun stuff. Pure in body, pure in spirit - etc. Most people think they're fairly strange.
Despite this strong dedication to their faith, my father and his siblings with whom I have discussed the issue, are all in favour of legally available assisted suicide for the terminally ill.
Incidentally, they are a family of doctors. And my paternal grandfather (a missionary doctor) passed at the age of 60, of bowel cancer. I never met him as I was born the same year, yet we seem to have formed a connection of sorts 31 years later.
Just pointing out this is not simply a Christian vs non-Christian debate, regardless of the main posters' backgrounds.
