This question seems to be incomplete. However, there´s enough information to find the right answer.
Answer: Rufus
Step-by-step explanation:
In "The Watsons Go to Birmingham" (1963), by Christopher Paul Curtis, although both Kenny and Rufus get bullied at school, Kenny becomes a bully himself when he follows Larry Dunn´s mockery of Rufus being poor. Kenny does redeem himself in the ens, as he realizes that he was wrong in doing that, and, furthermore, it could be somehow understandable that he wanted someone else to be picked on instead of him. But is definitely Rufus who shows to be a better character, because he never mocks anyone and is big enough of a person to forgive Keeny and give him a second chance. That´s why I sympathize more with Rufus.
