Is odysseus a hero?

Odysseus was a hero because he was loyal to his wife and children and saving his crew from cyclopes.

Ok I did a little research and I found this article.

In the spiritual sense Odysseus is a hero, because he remains faithful and loyal to his wife and household. Although he has been wandering away from home for almost twenty years, the only thing that keeps him alive is the thought of his wife and son that are back at home waiting for him.
