Atticus's norm

Atticus follows the personal norm because he was willing to defend Tom Robinson's case. Everyone thought that was unright because Tom is black and they should not get a lawyer. But, Atticus Knows what is right and agrees to defend him. This tells me that Atticus doesn't care what people say, he cares what is right and proves everyone else he is a nice guy. And because he is doing what is right Cal, Tom, and the whole First Purchase appreciates and respects him.
