Atticus Finch is a fictional character in the novel <em>To Kill a Mockingbird</em> (1960) by Harper Lee. Atticus is a lawyer that lives with his children in Maycomb County, Alabama. The character is based on the author's father, Amasa Coleman Lee. His story is similar to that of Atticus, as he was also a lawyer that represented black defendants in a highly publicized criminal trial.
Because he feels like he can't be himself, that he is not enough or does not have the potential to be something in the culture he is in.
