Good and evil are two of the most ambiguous terms in the English language. There are definite themes of good and evil in “To Kill a Mockingbird” by Harper Lee. Most define good as “morally right” and evil as “morally wrong or immoral.” These two definitions raise an important question. What is morality? Philosophically, morality can be described as a code of conduct that, given specified conditions, would be proposed by all rational people. So, if morality is a code proposed by all rational people, are immoral people irrational? Or do they believe in a different code established by them and other like-minded people? How is morality judged? Should the morality of an action be judged by the motivation for the action or the consequences of the action? Morality as a philosophical construct is very ambiguous and is debated by many philosophers. To conceptually understand good and evil, one must first fully understand morality (Gert 1-2). The following is an excerpt from “Beyond Good and Evil: Chapter V (Natural History of Morals); “There are moral systems that have the purpose of justifying their author in the eyes of others; other moral systems aim to reassure him and make him self-satisfied; with other systems he wants to crucify and humiliate himself, with others he wants to take revenge, with others he wants to hide, with others he glorifies himself and confers superiority and distinction, this moral system helps its author to forget, that system makes him, or something about him, forget, many moralists would like to exercise power and creative agency over humanity, many others, perhaps, Kant above all, make us understand with his morality that "what is estimable in me is... .... half of the paper.. ....having tested their faith in the goodness of man. Both believed in the good nature of man, which is a testimony to the goodness of man itself. Morality is an ever-changing landscape of nature of humanity will always be in question, but there will always be people like Atticus and Scout who will help see the goodness of man.
