The pardoner is really bad and this is admitted by him.
Explanation:
The pardoner admits that he acts out of greed and hypocrisy. He recognizes that he is a bad person, a crook, who has no remorse for twisting the faithful and exploiting the offerings they give to the church. The padorner's lack of remorse is because he is so used to being a crook that he cheats automatically, without thinking twice, even though he knows it's a sin.
