Have you read the book to kill a mockingbird?

I need 1 quote from the book that show Atticus finch is a hero.

"You know what we want," another man said. "Get aside from the door, Mr. Finch."

"You can turn around and go home again, Walter," Atticus said pleasantly. "Heck Tate's around somewhere."

"The hell he is," said another man.

" ... Called 'em off on a snipe hunt ... Didn't you think about that, Mr. Finch."

"Thought about it, but didn't believe it. Well then," my father's voice was still the same, "that changes things, doesn't it?"
