this is one of those grey areas. Personally if a terminally ill person wishes to end thier own life, I don't see the harm. However if you are not terminally ill then we as a society have a responsibility to prevent you from doing so and getting you psychatric help. My only concern is that the "actual wishes" of the person are followed. None of this "they told me once" crap. If that was the standard my wife would have me put down for sprainig my ankle. So if you really want to make your wishes known, put it in writing.
