Gloucester's younger illegitimate son is an opportunist, whose ambitions lead him to form a union with Goneril and Regan. The injustice of Edmund's situation fails to justify his subsequent actions. Edmund rejects the laws of state and society in favor of the laws he sees as eminently more practical and useful — the laws of superior cunning and strength.
Edmund's desire to use any means possible to secure his own needs makes him appear initially as a villain without a conscience. But Edmund has some solid economic impetus for his actions, and he acts from a complexity of reasons, many of which are similar to those of Goneril and Regan. To rid himself of his father, Edmund feigns regret and laments that his nature, which is to honor his father, must be subordinate to the loyalty he feels for his country. Thus, Edmund excuses the betrayal of his own father, having willingly and easily left his father vulnerable to Cornwall's anger. Later, Edmund shows no hesitation, nor any concern about killing the king or Cordelia. Yet in the end, Edmund repents and tries to rescind his order to execute Cordelia and Lear, and in this small measure, he does prove himself worthy of Gloucester's blood.
