The evolution of morality

Which of the following people would you say is the most admirable: Mother Teresa, Bill Gates or Norman Borlaug? For most, it's an easy question. Mother Teresa, famous for ministering to the poor in Calcutta, has been beatified by the Vatican, awarded the Nobel peace prize and ranked in a US poll as the most admired person of the 20th century. Bill Gates, infamous for giving us the Microsoft dancing paper clip, has been decapitated in effigy on "I Hate Gates" websites. As for Norman Borlaug … who the heck is Norman Borlaug? Yet a deeper look might lead you to rethink your answers. Borlaug, father of the "Green Revolution" that used agricultural science to reduce world hunger, has been credited with saving a billion lives, more than anyone else in history. Gates, in deciding what to do with his fortune, determined that he could alleviate the most misery by fighting everyday scourges in the developing world such as malaria, diarrhoea and parasites.
