From what book of chapter 5?
There are several things that distinguish heroes from monsters, especially in classical literature. Heroes and monsters are very highly contrasted through the dichotomy of good and evil. Heroes are often wholly good; monsters are often wholly evil. Being "good" entails protecting the wellbeing of others, and being "evil" means causing destruction and harm to others. They are also very starkly different in their physical appearance and personal attributes. Heroes, especially Beowulf, are bold, strong, physically fit, usually handsome, brave, wise, etc. Monsters are usually grotesque, horrifying, oversized, etc. Hope this helps.
Troy Davis was not allowed to submit to the lie detector to prove his guilt before being executed, as a last resort to avoid lethal injection. His defenders accused the Court of racial discrimination.
Davis´s attorney, Stephen Marsh, has commented that the Georgia department of corrections rejected the request to take the polygraph test. However, until the last minute Davis, did not recognize himself guilty of the murder of police officer Mark McPhail in 1989.
In spite of the doubts about the sentence, lack of real evidence of Davis´s participation in that murder and numerous social protests, the supreme court of the United States rejected the last request of clemency.
In both cases we can infer, although the country fights in order to defeat the racism, is a currently present problem.
