Macbeth is one of the many masterpieces produced by William Shakespeare. This tragedy is a shorter work that most of Shakespeare's plays. The drama centers on ambition, murder, guilt, and revenge. Behind the scenes are three witches who plant the seed of power into the mind of Macbeth, a Scottish thane, who is encouraged by his wife to gain illegitimate power. Indeed, Lady Macbeth is one of the most cruel of women found in literature. The lessons to be learned from this drama are timeless. The guilty conscience becomes capable of all sorts of wickedness and treachery, and the result will be ruination and damnation in this present world.
