Deal with the distinctions between active/passive and voluntary/involuntary euthanasia, and differentiate them form both doctor-assisted suicide and refusal of life-sustaining treatment. Is there a morally significant difference to you between letting die by letting nature take its course and killing a patient if they are bound to die very soon anyway? What of the use of morphine drips? Is it active euthanasia if upping the dosage leads to cessation of breathing and heartbeat? Should the medical profession admit that this is active euthanasia or continue to regard it as mainly pain relief when dying? Do we have de facto legalized active euthanasia if using morphine drips routinely kills people? Give reasons for holding your view.
