“mercy killing” is justified for “an incorrigible ‘human vegetable,’ whether spontaneously functioning or artificially supported, [who] is progressively degraded while constantly eating up private or public financial resources in violation of the distributive justice owed to others.” Joseph Fletcher, “Ethics and Euthanasia,” in Horan and Mall, eds., Death, Dying, and Euthanasia, p. 301.
"People [with children with Down's syndrome]... have no reason to feel guilty about putting a Down's syndrome baby away, whether it's "put away" in the sense of hidden in a sanitarium or in a more responsible lethal sense. It is sad; yes. Dreadful. But it carries no guilt. True guilt arises only from an offense against a person, and a Down's is not a person."[3]
