Callahan argues that voluntary active euthanasia is morally wrong and should be illegal. It moves medicine beyond its role of promoting health by involving issues of happiness and determining what lives are worth living. Callahan addresses four common arguments in favor of euthanasia: that it respects patient autonomy and self-determination; that there is no difference between killing and letting die; that it is unlikely to lead to bad consequences; and that it is compatible with medical practice. However, the document also evaluates some of Callahan's responses and points out potential issues with his positions.
