Name a character in To Kill a Mockingbird that shows courage.
I already have three examples: Atticus, who defends Tom Robinson despite knowing Tom will be pronounced guilty; Ms. Dubose, who attempts to break her morphine addiction before her death; and Boo Radley, who on more than one occasion ventures out of his house.
If you could name another character that is courageous, I would be greatly thankful.
You already have chosen the three characters from To Kill a Mockingbird who are most widely considered the most courageous in the novel. I would also suggest that Jem often shows courage in the story. He risks another shotgun blast or mutilation by Boo when he returns to the Radley house to retrieve his lost pants. He stands up to Atticus outside the jail in front of the impending lynch mob. And he tries to protect Scout when he does his best to fight off Bob Ewell's attack on the two children. Another character is Dolphus Raymond, who shows his own personal courage with his choice to live his life his own way--with his African-American girlfriend on the black side of town. He loses the respect of the white populace of Maycomb in the process.
