Justice, according to Plato, is “rendering to each his due” (Republic, Bk. 1). We might suppose that what people are due is a matter of what people are owed, either because they deserve it or because they have a moral right to it. Suppose we plug these ideas into consequentialism. Then we get the theory that things should be assessed in terms of not only how much welfare results but also the extent to which people get what they deserve and the extent to which moral rights are respected.
