Who are three characters in the book that were oblivious to the harm they caused in To Kill a Mockingbird?
Mayella Ewell did not realize that her actions led to the death of Tom Robinson and the destruction of his family. Mayella, in her ignorance, thought that if she committed any wrongful act it was only that she kissed a black man. She did not see that her accusations against him and her steadfast refusal to accuse her father of abuse were actions that led directly to Tom's death. She did not consider Tom a human being on equal footing with herself because she was white and he was black. Her father, Bob Ewell, was the same way only to a greater degree. Whereas Mayella was lonely and ignorant, Bob was lazy and mean. Bob knew he was hurting Tom but he was unaware of how much his racism would hurt himself and his family. Bob was just too self-centered, dumb, and mean to care. He also never realized that his actions almost led to the exposure of Arthur "Boo" Radley who was so shy and backward that public exposure would have been very harmful. Finally, Nathan Radley (and his father) never realized the harm they caused to Arthur Radley. Because Arthur was never given the psychological help or even the simple understanding that he needed as a boy, he was locked away at home and that led to him being the recluse that he was.
