下列是英文写的五个反对理由和四个支持理由,不知有用否^-^various arguments for and against arguments include: Physicians are supposed to save people, not kill them; Life is invaluable, therefore no criteria could justify death; Euthanasia pre-empts attempts of finding medicine for geriatric diseases; Three fallacies render applying euthanasia mistaken or unnecessary: the patient could have improved unexpectedly if no euthanasia had been applied, the diagnosis may have been incorrect, or new cures could appear after the patient is euthanised; and, euthanasia encourages killing the elderly, which ‘does not tally with the Chinese tradition of filial piety’.Supporting arguments include: a good death is a patient-right; euthanasia benefits the family of the patient if it relieves the family from financial and social burden; It befits the good of society, as it prevents wasting of human and material resources; and, the phenomenon of euthanasia belongs to the realm of highly evolved civilisations, together with other concepts, such as eugenics, good education, health, and a long and high quality life.
