 It is important to emphasize the motive of benefiting the person who is assisted to die because well-being is a key value in relation to the morality of euthanasia (see Section 3 below). Nonetheless, the defensibility of the contention that someone can be better off dead has been the subject of extensive philosophical deliberation. Those who claim that a person can be better off dead believe this to be true when the life that remains in prospect for that person has no positive value for her (a possibility which is discussed by e.g., Foot, 1977; McMahan 2002; Bradley 2009), whereas some of those who hold that a person’s life is inviolable deny that a person can ever be better off dead (e.g., Keown in Jackson and Keown 2012). A Kant-inspired variant on this latter position has been advanced by Velleman (1999). He considers that a person’s well-being can only matter if she is of intrinsic value and so that it is impermissible to violate a person’s rational nature (the source of her intrinsic value) for the sake of her well-being. Accordingly, he holds that it is impermissible to assist someone to die who judges that she would be better off dead and competently requests assistance with dying. The only exception is when a person’s life is so degraded as to call into question her rational nature, albeit he thinks it unlikely that anyone in that position will remain competent to request assistance with dying. This position appears to be at odds with the well-established right of a competent patient to refuse life-prolonging medical treatment, at least when further treatment is refused because she considers that her life no longer has value for her and further treatment will not restore its value to her. (For further reasons to reject arguments for the inviolability of the life of a person, including Velleman’s, see e.g., McMahan 2002; Young 2007; Sumner 2011.)
