Power and corruption are some of the major themes presented in Macbeth. The story deals with these themes by showing us how Macbeth's actions have grim consequences which ensure in poor results, such as Macbeth's complete change of character. In one of the first few scenes of the play, the captain states for "brave Macbeth well he deserves that name", showing us that Macbeth is loyal to the king for killing the villain. The captain's statement also shows that he is a good and well respected soldier in Scotland. Later, Macbeth and Banquo meet the witches who predict that Macbeth will become "Thane of Cawdor and king hereafter". When Macbeth "starts", it reveals that he had already considered becoming king before, but did not take any action because he knew it was morally incorrect. However, after hearing the witches' foretelling that
Although Macbeth and Lady Macbeth are powerful in their corruption, they are unable to fight against nature forever. Their sick deeds, manifested in the land, came back to haunt them literally as well as figuratively, ultimately leading to their separate demises in the form of divine retribution. Macbeth is defeated by the forces of Malcolm, who has never been with a woman, and Macduff, who “was from his mother’s womb / Untimely ripped” (-16). Both men are untainted by the kind of corrupting force that Lady Macbeth had exerted on her husband. Malcolm becomes a monarch with the right to rule under James I’s theory of kingship, both because he is the son of Duncan, who was a true king, and because he has not murdered the innocent or otherwise gone against nature to gain his position. Malcolm is sanctioned by God, able to act as the head to his kingdom in a way that Macbeth cannot. With Macbeth’s death and Malcolm's ascension to the throne, the natural order is restored and the land can begin to heal itself under the guidance of a king who is capable of compassion and care for his kingdom.
Louisiana's culture of corruption, by contrast, is flamboyant and shameless. Earl Long once said that Louisiana voters "don't want good government, they want good entertainment." He spent part of his last term in a mental hospital, where his wife had him committed after he took up with stripper Blaze Starr. When Sen. Allen Ellender died in office in 1972, Gov. Edwards didn't try to auction of his seat. He appointed his wife, Elaine, possibly to get her out of town. When Edwards ran for governor in 1983, he said of the incumbent, "If we don't get Dave Treen out of office, there won't be anything left to steal." (He also memorably said Treen was so slow it took him an hour and a half to watch 60 Minutes .) Raised among figures like these, Louisianans tend to accept corruption as inevitable, to be somewhat proud of it, and to forgive it easily.
