Lying is one of the broadest character flaws; ranging from white lies to cruel deception.

A good story has a protagonist, goals, and opposition. Opposition includes obstacles and forces of nature, but typically opposition also takes the form of a character. Sometimes the opposition is another protagonist, leaving the audience to choose who they want to root for, but many stories include at least one villain, a character that is definitively “wrong”. Villains can be narrative or mechanical.
