Both the Pardoner's Tale and his Prologue discuss morality and vices. Both define what is wrong or sinful. However, one is described through dictation, while the other is described in a story. The Pardoner seems to be a representation of Jesus, who told crowds the word of God, but did it through parables. Another difference is that the Prologue focuses more on all types of sin, whereas the actual tale teaches not to have avarice or greed.
The Pardoner is very much a hypocrite because he tells a story with a moral that teaches others not to be greedy when he himself is hoarding money from sinners by selling forgiveness. The Pardoner's Tale is different from The Miller's Tale and The Knight's Tale because both storytellers of the other tales actually represented their stories. The Knight taught through his tale of the importance of logic and correct forms of prayer, something expected of a Knight. The Miller, a drunk, tells a tale of lust, immorality, and lechery; even the host was aware that something vulgar or wrong would come out of his mouth. However, the Pardoner, who teaches what is wrong with having greed, actually commits sin himself.
