How does the tale of the rioters help the pardoners make sales?

The tale of the rioters appeals to the Pardoner's audience by using themes of greed, death, and morality, which captivates their interest. By exploiting their fear of divine punishment and offering pardons and relics for sale as solutions, the Pardoner can persuade the audience to purchase these items in hopes of absolving their sins and avoiding a similar fate as the characters in the tale.
