BOO RADLEY. Boo's heroism becomes evident at the end of the novel when the neighborhood's "malevolent phantom" comes to the rescue of the children. Boo has apparently been keeping an eye on "his children," and he fights off Bob Ewell, eventually killing him. Sheriff Tate refuses to name Boo as Bob's killer, instead believing that
"... taking the one man who's done you and this town a great service and draggin' him with his shy ways into the limelight--to me, that's a sin." (Chapter 30)
TOM ROBINSON. Tom shows courage when he innocently agrees to enter the Ewell house--it was a dangerous thing for thing for any black man in the 1930s to enter a white man's home without permission--to help Mayella. It takes moral courage to take his chances in a white man's court and to speak the truth after other testimony has condemned him. It also took personal bravery to try and escape from the prison yard, though foolhardiness would be a better description.
"And so a quiet, respectable, humble Negro who had the unmitigated temerity to 'feel sorry' for a white woman has had to put his word against two white people's." (Atticus, Chapter 20)
ATTICUS FINCH. Atticus does not consider killing the mad dog an act of bravery, but his children do. He also shows courage by agreeing to defend Tom Robinson, knowing that he and his children may face danger for doing so. Atticus displays a quiet courage by refusing to lower himself to Bob Ewell's standards and fighting him in public. But Atticus's heroic nature is best displayed when he stands up to the lynch mob at the jail.
"It's all over town this morning... all about how we held off a hundred foks with our bare hands..." (Dill, Chapter 16)
