At the beginning of the play, Gloucester appears weak and foolish, easily fooled by Edmund. In Act I, his boasts about easy conquests misleads the audience into dismissing Gloucester as a silly old man; but in this scene, the earl seems worthy of the king's allegiance. Gloucester proves that he is willing to sacrifice his own life for the king by disobeying Regan and Cornwall. This genuinely heroic behavior sets Gloucester apart from Edmund. An opportunist, Edmund takes advantage of his father's trust, seizing the chance to win Cornwall's favor. Betraying his father will provide Edmund with the position and wealth he craves. Acting without hesitation, Edmund sets out on a course that belies his breeding; a triumph of conscience is not a likely prospect in his unfolding treachery.
