What are some ways that Atticus showed empathy towards Tom Robinson and his family?

In chapter 15 of To Kill a Mockingbird, evidence can be found of Atticus showing empathy towards Tom Robinson. Several men arrive at Atticus's house to discuss concerns about Tom being moved to the Maycomb County jail. Atticus says, "that boy may go to the chair, but he’s not going till the truth’s told." Atticus knows he is fighting a difficult battle, but he is determined to defend Tom.
In chapter 23, Atticus is discussing Tom's possible appeal with Scout and Jem. He provides another example of empathy towards Tom when he states, "In our courts, when it’s a white man’s word against a black man’s, the white man always wins." While Atticus's closing arguments in the case highlight many contradictions and inconsistencies in the testimonies of Bob and Mayella Ewell, Tom is found guilty.
Atticus brings bad news to Aunt Alexandra's Missionary Tea one day in chapter 24. Speaking to Calpurnia, he shares that Tom has been shot seventeen times while trying to escape. Atticus states, "They didn’t have to shoot him that much. Cal, I want you to come out with me and help me tell Helen." Atticus feels that he should break the news to Tom's wife, providing another example of empathy this time to Tom's family.
In a fourth example also found in chapter 24, Atticus demonstrates empathy to Tom's plight when he says, "I guess Tom was tired of white men’s chances and preferred to take his own." Tom's attempt at escape is a result of feeling hopeless. Atticus understand that Tom experiences much racism and bigotry. Respecting him enough to tell him the truth, Atticus seems to feel that giving Tom a false sense of hope for appeal would have been inappropriate.
