Answered by Aslan. As Atticus has explained to Scout many times about this, He is doing this becasue he values equailty and justice. He believes that everyone is equal and therefore just because Tom Robinson is black, doesn't mean that he should not defend him.e says to Scout many times, if he did not defend this man, he could never tell Jem or her (Scout) not to do something. He has to set a good example for his children and if he expects them to do something or follow certain values, then he must display them first.
The book doesn't clearly state why, but we can suppose two reasons: Atticus didn't like to show off in front of other people because he was very discreet by nature. Atticus was a very kind and gentle man and probably didn't like the idea of killing any animal out of sport.So in spite of his excellent marksmanship, shooting and killing animals didn't appeal to him; moreover, any form of violence certainly doesn't adhere to Atticus Finch's character profile.e is talking about Mrs. Dubose. He says: I wanted you to see what real courage is, instead of getting the idea that courage is a man with a gun in his hand. it's when you know you're licked before you begin but you begin anyway and you see it through no matter what. You rarely win, but sometimes you do.
