Euthanasia has many definitions. The Pro-Life Alliance defines it as: 'Any action or omission intended to end the life of a patient on the grounds that his or her life is not worth living.' The Voluntary Euthanasia Society looks to the word's Greek origins - 'eu' and 'thanatos,' which together mean 'a good death' - and say a modern definition is: 'A good death brought about by a doctor providing drugs or an injection to bring a peaceful end to the dying process.' Three classes of euthanasia can be identified -- passive euthanasia, physician-assisted suicide and active euthanasia -- although not all groups would acknowledge them as valid terms.
