What if Atticus' good morals were no more?

In the novel, To Kill a Mockingbird, by Harper Lee, Atticus has morals that are different than others during this time period. He raises his children to think fairly of everyone in a time when slavery still exists. "nigger-lover is just one of those terms that don't mean anything-like snot-nose. Its hard to explain-ignorant, trashy people use it when they think somebody's favoring Negroes over and above themselves. It slipped into usage with some people like ourselves, when they want a common, ugly term to label somebody" (Lee 144). When Atticus hears of any prejudice remarks or comments from his children, he is quick to correct and remind them that people are people no matter their skin color. "Naw, Jem, I think there's just one kind of folks. Folks" (Lee 304). Atticus has no shame in showing his concern for equal rights, especially to his kids. When Scout asks if Atticus is a "Nigger-lover" he says "I certainly am. I do my best to love everybody. . . I'm hard put sometimes-baby, its never an insult to be called what somebody thinks is a bad name. It just shows how poor that person is, it doesn't hurt you" (Lee 144). Atticus is obviously teaching his kids the right morals, but what if he hadn't? What if Atticus did not teach his kids good morals simply because he was prejudice himself? What would change about the story if Atticus was not fair?
