In my opinion, If Jackie Robinson fought back all the racism and discrimination, then they would have gotten the reaction they wanted out of him to prove that he was an aggressive person and not needed on the team due to being a person of color. The idea would be improper today because we don’t view people as their skin color and even though people are still discriminative and racist, it’s not as severe as this time we’re living in today.
In Chaucer's "The Canterbury Tales" the reader is introduced to the Pardoner in "the Pardoner's Tale". What is ironic about the Pardoner is that he would often preach that money was the root of all evil, but then he would sell pardons (official documents that pardoned sins).
Repetition helps exaggerate a point that the author is trying to convey. It highlights the main idea of what that character in the story is trying to let readers understand when stating such phrases.
