- Political motivations: Polyneices was a threat to the power of his brother Eteocles, who was the rightful heir to the throne of Thebes. By dishonoring Polyneices, Eteocles could consolidate his power and prevent any potential challenge to his rule.
- Personal motivations: Eteocles may have also been motivated by personal hatred or jealousy towards Polyneices. Polyneices was a skilled warrior and a charismatic leader, and his return to Thebes could have threatened Eteocles' position as the dominant brother.
- Social motivations: The people of Thebes may have been divided in their loyalties between Eteocles and Polyneices. By dishonoring Polyneices, Eteocles could have appeased those who supported him and strengthened his hold on the city.
- Religious motivations: The gods of Thebes may have also played a role in motivating the dishonoring of Polyneices. Eteocles may have believed that the gods favored him and would support his decision to treat Polyneices in such a way.
