In To Kill a Mockingbird, how do the adults deal with the outcome of the trial?
Alexandra has the attitude that of course this is what would have happened, but she is disappointed for Atticus' sake. She does deeply care about her brother. She was also upset that he would allow the children to be exposed to the trial:
“I’m sorry, brother,” she murmured. Having never heard her call Atticus “brother” before, I stole a glance at Jem, but he was not listening.
“I didn’t think it wise in the first place to let them—”
“This is their home, sister,” said Atticus. “We’ve made it this way for them, they might as well learn to cope with it.”
“But they don’t have to go to the courthouse and wallow in it—”
Atticus is exhausted emotionally and physically. He also feels the pain of watching justice denied as evidenced by these words:
“I’m not bitter, just tired. I’m going to bed.”
“Atticus—” said Jem bleakly.
He turned in the doorway. “What, son?”
“How could they do it, how could they?”
“I don’t know, but they did it. They’ve done it before and they did it tonight and they’ll do it again and when they do it—seems that only children weep. Good night."
Bob Ewell spits tobacco in Atticus' face. He obviously is not over the fact that Atticus smeared his reputation as if there was much of any positive reputation to begin with.
Maudie Atkinson honors Atticus with her speech to the children and recognizes his ability to act on behalf of the entire community in these words:
“I simply want to tell you that there are some men in this world who were born to do our unpleasant jobs for us. Your father’s one of them."
“We’re the safest folks in the world,” said Miss Maudie. “We’re so rarely called on to be Christians, but when we are, we’ve got men like Atticus to go for us."
The Negro community is appreciative and shows it by flooding Atticus with food:
Calpurnia said, “This was all ‘round the back steps when I got here this morning. They—they ’preciate what you did, Mr. Finch. They—they aren’t oversteppin‘ themselves, are they?"
The ladies of Maycomb respond at the Missionary Tea by noting how dreadful their black servants are. This demonstrates that they still have great prejudice even though the think they have done the black community a favor.
