In completely empathizing with the Main Character of a story, we practically become this person. There are certain dynamics we expect to be able to determine about a Main Character as part of experiencing things from his point of view. One of these is called Main Character Resolve.

Main Character Resolve answers the question “Does the Main Character ultimately Change or Remain Steadfast?” At the beginning of the story the Main Character is driven by a particular motivation. When the story ends, he will either still be driven by the same motivation (Steadfast) or have a new motivation (Change).

Main Character Resolve really describes the relationship between the Main Character and the Obstacle Character. The impact of the Obstacle Character is what forces the Main Character to even consider changing. If the Main Character ultimately does change, it is the result of the Obstacle Character’s effect on the Main Character’s perspective. If, on the other hand, the Main Character remains steadfast, then his impact on the Obstacle Character will force the Obstacle Character to change.

Some Examples:
Star Wars: Main Character: Luke Skywalker (Change)
Obstacle Character: Obi Wan Kenobi (Steadfast)

The Story of Job: Main Character: Job (Steadfast)
Obstacle Character: The Devil (Change)

To Kill A Mockingbird: Main Character: Scout (Change)
Obstacle Character: Boo Radley (Steadfast)

The Fugitive: Main Character: Dr. Richard Kimble (Steadfast)
Obstacle Character: Agent Sam Gerard (Change)

It should be noted that the Obstacle Character need not even know he is having that kind of effect on the Main Character. He may know, but he may easily not even be aware. Main Characters are defined by the point of view, Obstacle Characters by the impact on that point of view.
