1Racial injustice
Tom Robinson is accused by a white woman, tried before a jury of poor white farmers, and convicted despite a crippled left arm that makes the crime physically impossible. The black balcony stands for Atticus as he exits; the kitchen fills with food; Tom dies in a hail of seventeen bullets. The machinery works exactly as designed—the jury just won't look at what it's doing. The book's point: the law can be formally fair and still be an instrument of racism, and a good man's best defense only buys a slower verdict.

2Courage
Atticus separates courage from guns. Mrs. Dubose, dying, breaks her morphine addiction on her own terms, and Atticus calls her the bravest person he knew: courage is 'when you know you're licked before you begin but you begin anyway and you see it through no matter what.' He takes Tom's case for the same reason—he was 'licked a hundred years before' he started. The book's point: real courage is moral, unglamorous, and measured in what you do when winning isn't on the table.

3Empathy
Atticus's rule—climb into someone's skin and walk around in it—gets tested all book. Scout learns it with Walter Cunningham, feels Mayella's loneliness during her testimony, and finally stands on Boo Radley's porch and sees the whole story as he lived it. The book's point: understanding isn't sympathy from a distance; it's the discipline of imagining another life completely, and it's the only real antidote to a town's certainties.

4Innocence lost
Jem is the one the verdict breaks. He believes the system will work because the evidence is clear, and when it doesn't, he can't stop crying: 'It ain't right, Atticus, but I can't understand it.' Dill's answer is to become a clown; Scout's is to grow up. The book's point: childhood ends the moment you watch adults choose injustice with their eyes open—and the question is what you build from the wreckage.

5Class and codes
Maycomb runs on a caste system: Cunninghams too proud to take charity, Ewells allowed to hunt out of season, a black community that fills a white family's kitchen with food. Mayella's crime isn't the lie—it's breaking 'a rigid and time-honored code of our society' by desiring Tom. The book's point: prejudice isn't just racial; it's a whole architecture of who owes what to whom, and the people lowest on the ladder defend it hardest.
