Many people confuse Protagonist with good guy and Antagonist with bad guy. Which is not always the case.

Protagonist is: 1. the main character in a novel, movie or play. 2. An important person involved in a competition, conflict or cause.

Antagonist is: a person who opposes another.

Things to consider then:

So with those definitions Do you now have two protagonists?
Do you need a new antagonist?
Is your protagonist considered an anti-hero?

Just some more food for thought.
