In the margin explain why the pardoner characterizes himself as a pigeon

 The Pardoner takes as his text that "Love of money is the root of all evil," yet he emphasizes how each relic will bring the purchaser more money; in emphasizing this, he sells more and gains more money for himself. Thus, his text contains a double irony: His love for money is the root of his evil, yet his sales depend upon the purchaser's love of money. Furthermore, his technique of relying upon basic psychology by selling only to the good people brings him more money. His sermon on avarice is given because the Pardoner is filled with avarice and this sermon fills his purse with money. 

Are you asking for a opinion ? if so i believe that a speaker should be genuine and honest about what they're saying and should be factual
