This is a difficult one. In general, I am against euthenasia and suicide. These are really two different subjects. Most of the time I look upon suicide and suicide attempts as symptomatic of depression, a medical and psychological illness which can be treated. For euthenasia, I can see only one general set of circumstances in which it could be allowed. First off, the patient has to ask for it in a state while they are "of sound mind". I don't know how to judge when someone is "of sound mind" but it seems to me that this is something that a person would need a good while to think about during a time when they could actually concentrate on it, appreciate the reprecussions and reasonably evaluate the alternatives. Secondly, the euthenasia option would only be allowed when the patient is on death's door. That is, the patient has been diagnosed as having some short amount of time left to live, perhaps something on the order of a few days to a week. Thirdly, the patient must be experiencing severe, prolonged, physical pain. All of these conditions having been met this, the physician should be allowed to perscribe sufficient pain medication to cause a cessation of the patient's pain, even if that may exceed normal dosage. If a lethal dose is what is required to stop the pain, if the patient has previously given the ok for such a dose, and if the patient's chances for recovery (such that the prolonged, sever pain will moderate or cease and the patient will have a longer projected time (months?) to live) are nil, then a lethal dose should be allowed. My understanding is that this sort of thing goes on regularly in the current environment. I think that allowing euthenasia under less strict circumstances is potentially allowing murder and that the patient, under those circumstances, would likely be better served by psychological assistance.
