Atticus Finch, a wise father and lawyer, demonstrates courage by defending Tom Robinson, an African American man wrongly accused of a crime, despite knowing he'll face backlash from his community. Despite threats and insults from Bob Ewell, Atticus refuses to back down, showing that true courage means sticking to your principles no matter what.
Atticus's children, Scout and Jem Finch, also learn about courage through their experiences.
