Essayist: Many people are hypocritical in that they often pretend to be more morally upright than they really are  When hypocrisy is exposed, hypocrites are embarrassed by their moral lapse, which motivates them and others to try to become better people
On the other hand, when hypocrisy persists without exposure, the belief that most people are good is fostered, which motivates most people to try to be good
The hiding of hypocrisy is a better way of motivating people to try to be good than is the exposing of it.
