Congrats on your imaginative choice of topics. A rereading of both novels should provide you with plenty of quotes and support for your thesis. Be sure to express that in both cases, the objects of their fears were imaginary--a lifeless corpse that could do no physical harm, and an unseen man who presented no real danger. Instead of evil, they both were actually heroic--a parachutist who dies doing his military duty, and a recluse who summons the courage to "come out" and save the Finch children from harm.
TO KILL A MOCKINGBIRD.
- "The Radley House was inhabited by an unknown entity the mere description of whom was enough to make us behave for days on end."
- Boo was a "malevolent phantom. People said he existed, but Jem and I had never seen him."
- " '... he'll kill us each and every one' " Jem warned Dill. " 'Don't blame me when he gouges your eyes out.' "
- When Scout finds out that it was Boo who placed the blanket on her shoulders on the night of Miss Maudie's house fire, "My stomach turned to water and I nearly threw up."
LORD OF THE FLIES.
- "They lay there listening, at first with doubt and then with terror to the description the twins breathed... Soon the darkness was full of claws, full of the awful unknown and menace."
- "The vivid horror of this, so possible, and so nakedly terrifying, held them all silent."
