I believe people are more good than bad. When Obama said this he was only repeating what many have said before. Another version: I believe there are more good people in the world than bad people. What does not follow, though, is that, thanks to the numbers, the good will prevail. What cannot be left out of account is that, under certain circumstances, the bad can get the good to act badly, and furthermore, in order to achieve certain goals—victory in wartime, for example—getting the good to act badly rises to the level of a necessity.
