Who admits the blame for Edmund treachery?

Edmund's treachery is primarily attributed to his own ambition and desire for power. However, characters like Gloucester and Lear also bear some blame as they fail to recognize and address the manipulative nature of Edmund. Their blindness to his schemes allows his treachery to flourish unchecked, ultimately leading to tragic consequences. Thus, while Edmund is the architect of his betrayal, the failure of others to see through his deceit contributes to the unfolding drama.
