Macbeth and his wife show how bad the evil that can possess human souls is. But evil is not all powerful. On the one hand, Macbeth is the gloomiest of the great Shakespeare's tragedies; on the other hand, it's more encouraging than Hamlet, Othello or King Lear. In no other tragedy as in Macbeth the evil is confronted by so many people, and nowhere else they are so active. Shakespeare is the author of the world famous sonnets and plays: Romeo and Juliet, Hamlet, Macbeth and Othello, as well as comedies Twelfth Night, A Midsummer's Night Dream, Love's Labour's Lost, The Merry Wives of Windsor, The Two Gentlemen of Verona and As You Like It. William Shakespeare is the most performed playwright, the works of the great English poet have been on top of the world theatre stages for some centuries already.
