What are the defining moments of Atticus's leadership character in the movie To Kill a Mockingbird? This is based on the book Defining Moments by Joseph Badaracco Jr. What type of leadership traits does Atticus have? How did he model the way?

The character of Atticus Finch may not be considered a leader by some readers and viewers of the film. His leadership qualities are not manifested in the ways society expects. Atticus leads by example as a father, as a lawyer, and as a member of society.
First, Atticus has a clear sense of his principles and beliefs. By remaining true to those principles, he demonstrates integrity. Atticus also demonstrates that it takes more strength to exercise self-control than it does to lash out, which is often construed as weakness.
Throughout the story, there are countless examples of Atticus's leadership, but none is as defining as his decision to represent Tom Robinson. Scout asks Atticus if he'll win the case, and he tells her no, they won't win. When Scout asks her father why he's going to defend Tom if he isn't going to win, Atticus replies, "Simply because we were licked a hundred years before we started is no reason for us not to try to win." Regardless of the consequences, Atticus acts according to the dictates of his conscience.
