Euthanasia or mercy killing is the term applied to the painless killing of those suffering from an unbearable pain and an illness for which there is no cure. Advocates of euthanasia have urged that morality and wisdom consist not in the pursuit of life, but in the pursuit of a quality and conversely, it may be desirable to end a life that is irreparably blasted by a dreadful disease or degradation. Indeed the champions of euthanasia go to the length of questioning the very basis of the moral theory which holds that life is always good, death is always evil and its dubious inference that deliberate killing of an innocent human life is always wrong and impermissible. The contrary point of view is expressed by the anti-quality-of-life advocates in diversity of philosophies and moral positions ranging from the view that euthanasia is intrinsically-evil and a direct violation of God's supreme domination over. There are people who hold the view that euthanasia is almost wrongful because sentence or even painful experience is preferable to a permanent state of non-existence. A more plausible objection of the anti-euthanasia protagonists is that if euthanasia were permitted it would lead to a general decline in respect for life; a single instance of euthanasia would very probably lead to a slide, which is a dangerous misuse.
