Edmund's musings offer insight into his unhappiness. Edmund feels that each brother, equally loved, should share equally in his father's bounty. But there is no equality under the current law, and Edmund's ideal is not reality. Edmund asks why he is not as respected as his brother:
When my dimensions are as well compact,
My mind as generous, and my shape as true,
An honest madam's issue? Why brand they us
With base? With baseness? Bastardy? Base, base? (I.2.7–10)
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 willingness to seize what he wants invokes laws of nature, although not the natural laws familiar to Elizabethan audiences in a class-defined society. Instead, Edmund supports survival of the fittest, an animalistic nature not based on human morality and common decency. Edmund says that he will take what he deserves through wit, even if he is not entitled by birth. This resolve is an affront to the nature that Edgar addresses in his opening soliloquy; underestimating the force of nature will also prove critical to Edmund's downfall.
Edmund appears to be a villain without a conscience, selfishly driven to secure his own needs. Still, Edmund lacks the ill will of another of Shakespeare's villains, Iago, with whom Edmund is most often compared. In Othello, Iago acts without clear reason, since none of his suggested motives withstand a close examination. In contrast, Edmund has solid economic and emotional reasons for his actions. Edmund may also have overheard his father describe the "good sport at his making" (I.1.22). If so, Edmund's actions reveal a desire for personal revenge.
