BOO RADLEY. Prejudice and superstition surround Maycomb's "malevolent phantom" who is never seen but is believed to come out at night to wreak havoc upon the town. The townspeople believe him to be mentally disturbed (and perhaps he is), and Boo must sense this, choosing to remain inside the house long after his parents' deaths to avoid the stares and glares that would undoubtedly await him. Superstitions also abound about Boo, particularly that he has poisoned the pecans on the Radley tree in the hopes of luring young schoolchildren to an early death.
TOM ROBINSON. Tom is found guilty of the charges against him even though it is obvious that his physical limitations prevent him from committing the crimes. Atticus understands long before the trial begins that "The jury couldn't possibly be expected to take Tom Robinson's word against the Ewells'," since a white man's word is always accepted over the word of a black man.
DOLPHUS RAYMOND. A wealthy white man who prefers the company of blacks, Raymond is scorned by the white citizens of Maycomb who believe he must be mentally unstable to act as he does. But the joke is on the people of Maycomb: Dolphus "deliberately perpetrated fraud against himself" because he knows the townspeople will "never, never understand that I live like I do because that's the way I want to live."
