Structural myths are said to be myths based on human emotion. These types of myths show the two sides of the human mind; the good side and the bad side. They show the divided self and the duality of human nature. Myths about Hercules show how the human mind can be both good and bad. Hercules did both good and bad things. One of the bad things he did was (in “Jason and the Argonauts”) he stole a broach pin from the treasure chamber of the god Talos. This sin caused his friend to be killed. Hercules knew that his friend was killed because of his sin, so to make up for it; he vowed to stay on the island until his friend was found.
