Why is motivation important when analyzing characters

The same should be true of our fictional characters. We should know them, how they do and should and typically behave. We should know what floats our lead character’s boat, what makes him do what he does, what gets him moving each day.

We should know the same things about the antagonist and, to a lesser degree, other characters who play major roles in the story or who get a lot of time with the reader.
