Atticus has taught Scout and Jem repeatedly not to judge others and instead to try and sympathize with them. He states "you never really knew a man until you stood in his shoes and walked around in them." He not only tells this to Scout and Jem but also shows this to them through his treatment of Tom Robinson and Mayella Ewell. He understands both Tom's predicament and Mayella's lonliness in such a way that he tries to do what is best for both of them during the trial. Scout shows she has learned this lesson through her sensitivity toward Arthur Radley after he rescues Scout and Jem from Bob Ewell. She understands his shyness and even goes so far as to make sure he sits in a place of low light in order to relieve his shyness.
