Cultural pluralism is one of the characters of contemporary world. People from disparate cultural backgrounds can make disparate moral judges on an act, taking place under the same circumstances. These different moral judgments can contribute to a kind of moral relativism in bioethics: disparate judgments would be equally right or valid depending on different cultural traditions.
