What mistake did Hades make?

Hades made the mistake of underestimating the power of love and desire when he abducted Persephone to the Underworld. His actions led to a significant backlash from both Persephone and her mother, Demeter, which resulted in the world experiencing famine and despair. Ultimately, his inability to consider the consequences of his actions demonstrated a lack of understanding of the bonds that connect individuals, leading to a compromise that altered the seasons.
