Conflict is almost certainly to remain a fundamental challenge for human societies. The fact that it can produce benefits for individuals, groups, and nations leaves one to conclude this is likely to continue. Many would probably concur that a number of the benefits outlined above are clearly positive outcomes (and not necessarily speaking only selfishly). Fighting injustice and forging identities are but two important roles of conflict. The challenge is to realize the benefits of conflict in such a way so as to minimize the many costs also associated with conflict.
Another kind of external conflict sets a character against the evil that dominates a society. In such kind of conflict, a character may confront a dominant group with opposing priorities. For instance, in Harper Lee’s novel “To Kill a Mockingbird”, an honest lawyer Atticus Finch goes up against the racist society in which he lives. Atticus has the courage to defend a black man, Tom Robinson, who has been falsely accused of a rape. Though Atticus has the support of a few like-minded people, most of the town express their disapproval of his defense of a black man.
