In fiction, conflict is usually between characters, even if there is a primary conflict with forces of nature. Where the conflict is primarily between characters, there is generally a main character who is basically good but who may have a flaw that gets in his way. A secondary character in opposition to the hero appears to the reader to be basically bad.

Satisfying conflict happens when the characters move towards each other, sometimes even exchanging characteristics. The hero learns and grows through dealing with his weakness and flaws. The foe softens and learns a lesson, too.

In nonfiction, the conflict is often a clash of ideas. The writer begins with a thesis. The antithesis is an opposing view. As the writer works through the arguments for each point of view, often a synthesis evolves.

Readers find it easier to stick with a writer who deals fairly with the opposition, who acknowledges problems in the thesis or strengths in the antithesis.
