What makes killing wrong? the implication of marquis’s view for the morality of abortion

This article highlights what makes killing wrong according to Marquis. Killing a human being is morally and legally prohibited, except in a few rare cases under which it is permitted and justified. Marquis claimed that it is unjustifiable to deprive a human being the future experiences he was bound to enjoy. Marquis’ claim that abortion is the same as killing a human being who is already born, and the difference lies only in the premise of the arguments. In conclusion, the arguments that justify or prohibit abortion are mainly based on biological and theological theories. The theory of personhood features prominently in these arguments, but Marquis omits them in his discussion on why killing is immoral. Life is precious to everyone including those unborn babies considered not to have an opinion; thus, it is necessary to center on appropriate ideals.
