Who is the novel's Protagonist? Antagonist? "Hero"?

I think that the monster is the protagonist and Victor is the antagonist because Victor is always out to get the monster. Victor wants to destroy the monster simply because he thinks he can. He uses the monter's crimes as a real reason to harm him. If anyone should be the "hero", then it should be the monster because he exhibits good character. He didn't get people to feel sorry for him like Victor did. He handled his own and didn't have help from anyone. Victor had the family and friends, but he took them for granted. "...my accumulated woes..(p.155)." Victor cared only about himself and ignored the people around him. The monster always took into consideration other peoples' feeling, which makes him a hero!
