Moral exemplars are often depicted as those who go to extraordinary lengths in preventing suffering and eradicating injustice. Thus, figure like Gandhi, Mother Theresa, and Martin Luther King are apt to be identified as moral saints in the sense of being the morally best people. However, any adequate conception of moral excellence must be broader and more complex.
