I would have to say Euthanasia is okay when the condition calls for it. Like my dad for instance, even though I don't like to talk about it I will....
My dad had COPD and Emphazyma(sp?), he was in the hospital for THREE WEEKS before he passed away. I remember sitting next to him in the hospital for three days straight only sleeping a total of four hours and whispering to him in the middle of the night to just let go. If there had been an easier way, I would have agreed to it. His condition was bad enough he had trouble breathing and was on oxygen. I remember him telling me I had say in what happened to him and as badly as I wanted to say to put him on life support, I couldn't let him be on a respirator for years to come knowing it would be difficult to pull him off even if his condition got better.
So if there had been an easier way to end his suffering than him laying in a hospital bed and taking at least four days to slip away, I would have been all for it.
However if someone just can't handle things and wants to die, then that's not natural and shouldn't be permitted. I've had two family members kill themselves and it's not right.
So I guess I'm only saying if there is no hope what-so-ever of their health getting better, then I would agree. However for a perfectly healthy person who has years ahead of them. It isn't right.
