> Somehow the idea that someone can be perfectly sane and not want to live as long as possible is inconceivable to people. You're confusing not wanting prolong life in a state of unbearable pain because of an incurable, terminal illness, and willful, intentional suicide or homicide. There is a very big difference. In medicine, a distinction is made between ordinary and extraordinary care. Ordinary care concerns the basic needs of the patient such as air, food, water. Extraordinary care concerns medical treatments meant to cure or otherwise treat the disease or disorder. Typically, neither a patient nor anyone else can deprive a terminally ill patient of ordinary care. However, when providing of such things constitutes an "undue burden", such as when the body is no longer able to digest food or absorb liquids and the offering of food and drink actually causes harm, the patient may refuse food. At that point, you are accepting your powerlessness in the current situation, i.e., one in which the patient is in a state from which he cannot recover and for whom death is imminent. Even treatments that may extend the life of the patient can be licitly refused by the patient if it would, again, pose an undue burden (for example, a weak, terminally ill patient may refuse CPR if his condition is such that the procedure, which is physically traumatic, while potentially able to extend the life of the patient by some small amount of time, would leave the patient in a state of great suffering during their last few hours). So extension of life at any cost is not the goal of most people who oppose euthanasia. Natural law theory is perhaps the most vehemently opposed to euthanasia and will serve as an excellent resource for considering these kinds of questions. I would caution you against making appeals to subjective feelings in a vacuum, which your examples attempt to do. This is dangerous because we are capable of feeling all sorts of things and being confused about all sorts of things. The crude subjectivism of our times puts excess emphasis on such things without understanding them in an objective context (which itself may be misunderstood or crudely understood).
