Can you give me at least three examples that express the theme "Courage is doing what is right, even when the odds of succeeding are poor" in To Kill a Mockingbird?
MRS. DUBOSE. Atticus believes that Mrs. Dubose "was the bravest person I ever knew." Her decision to rid herself of her longtime morphine habit before she died was a courageous one, knowing that
"... you're licked before you begin but you begin anyway and see it through no matter what."
ATTICUS'S DEFENSE OF TOM. Atticus knew he could not possibly win the Tom Robinson case, since no jury could be expected to accept the word of a black man over the word of a white man. He hoped to win on appeal, so the final verdict was not a surprise to him. However, Atticus decided to take the case, and he would do his best and see it through to the end in spite of the enemies he might make in the process.
BOO TO THE RESCUE. Boo must have known that he was risking his own life when he interceded between Bob Ewell and the attack on Jem and Scout on that fateful Halloween night. He had decided to be the children's friend and unseen protector many months before, and when he saw that Bob was intent on killing them, Boo made the decision to stop Bob. Although Bob was small and drunk, he was a strong and wiry man, so the likelihood of Boo succeeding was not a certainty. But there was no one else around, and Boo made the courageous decision to stop Bob, even if it meant he might be hurt or killed--or be forced to finally expose himself to "the limelight" of public scrutiny.
