Good point, but I think there are a couple of differences. 1) Generally, in most cases, that decision comes from a family member or someone with legal authority over the patient. 2) If a machine is required to keep them alive in all intent and purpose, and without that machine, all vital organs will shut down, is that person really alive? People with pacemakers/defibs can still live a full life using these machines, but a person on life support still isn't living any life other than just being alive. I'm from Michigan where we had Dr. Kavorkian (sp), and I support the notion of assisted suicide, but I would prefer it be from a completely different type of doctor, not the types who are charged with keeping people healthy and alive. I wouldn't want to be seen by a doctor who assists in suicide because any participation in a death is a traumatic experience for a person, and I wouldn't trust judgement with that kind of burden on it.
