In the Pardoner's Tale, is the central idea applicable in the real world?

The central idea of they Pardoner's tale is the way in which people preach one thing, only to do another. The Pardoner's tale in no way lines up with his behavior. This idea is completely applicable in the real world. There are many instances of people who advise or preach one thing, who in no way follow their own advice. Hypocrisy is no different or less visible today than it was in the days of Chaucer.
