The fast advance of medicine and life–extending technologies enable life to be prolonged 。But it’s this leap of technologies to prolong life and control dying that raises the controversial topic—euthanasia( 安乐死)or mercy killing.
People supporting mercy killing argue that euthanasia is humane because it helps to hasten the death of hopelessly ill patients，relieving them from the agonizing pain , which is good for both the doomed people and their families. For these people，staving off death is to compromise a fundamental value—the quality of human life. However，those who object to euthanasia think it is immoral to give up treatment or commit suicide with doctors’ assistance。In their opinions, that is nothing less than murdering.
IN fact, to continue or terminate life is a moral choice because it involves a decision about a fundamental human good , the preservation of life . After all, life is the mast precious asset that we have for creativity and productivity.
