Atticus is a man of integrity. He is a man who believes in fairness, truth, and justice. When dealing with Scout and Jem, Atticus impresses on them the right way to live. He corrects Jem and Scout for making fun of Boo Radley. He also makes Jem got to Mrs. Dubose house to read to her after Jem destroys her bushes. Atticus uses every incident as a teaching moment for his children.
"As a father Atticus is affectionate with Jem and Scout, ready with a hug when they need comfort and available to spend time reading to them. Although he allows his children freedom to play and explore, he is also a firm disciplinarian, always teaching his children to think of how their actions affect others and devising punishments to teach his children valuable lessons."
Atticus demonstrates his passion for equal rights by representing Tom Robinson, a black man accused of raping a white woman, when no one else would take the case. He believed every human being should have the right to a fair trial, be able to face his accusers and have the best available representation. He knows that Tom won't get a fair trial, but he does his best to defend Tom in spite of that fact.
