Courage is a key theme as well. Atticus shows great courage in defending Tom Robinson, knowing the social and personal risks involved. And the children also display courage as they learn about the world and try to make sense of the unfairness they see, like when Scout faces the angry mob outside the jail.
Atticus Finch from 'To Kill a Mockingbird' is extremely memorable. He is a paragon of moral integrity, a loving father, and a fearless lawyer. His calm and rational approach in the face of prejudice makes him an iconic character.
