I think yes but within reason.
I once read about a woman who had a problem with her stomach and evertime she ate she threw up and was in tremendous pain for most of her life. She had euthanasia and I think that that was the best thing to do for her. But, if someone had say a less serious condition and wanted to die, I doubt the doctors would allow it. If we had it free, it would be the new emo fad.
Yeah that sounds ridiculos but you never know.
