Thus Macbeth, and Richard the Third, King Henry the Sixth, and Richard the Second,—characters that, in their general description, and in common hands, would be merely repetitions of the same idea—are distinguished by traits as precise, though of course less violent, than those which separate Macbeth from Henry the Sixth, or Richard the Third from Richard the Second. Shakespear has, with wonderful accuracy, and without the smallest appearance of effort, varied the portraits of imbecility and effeminacy in the two deposed monarchs. With still more powerful and masterly strokes, he has marked the different effects of ambition and cruelty, operating on different dispositions in different circumstances, in his Macbeth and Richard the Third. Both are tyrants and usurpers, both violent and ambitious, both cruel and treacherous. But, Richard is cruel from nature and constitution. Macbeth becomes so from accidental circumstances. He is urged to the commission of guilt by golden opportunity, by the instigations of his wife, and by prophetic warnings. ‘Fate and metaphysical aid,’ conspire against his virtue and loyalty. Richard needs no prompter, but wades through a series of crimes to the height of his ambition, from ungovernable passions and the restless love of mischief. He is never gay but in the prospect, or in the success of his villanies: Macbeth is full of horror at the thoughts of the murder of Duncan, and of remorse after its perpetration. Richard has no mixture of humanity in his composition, no tie which binds him to the kind; he owns no fellowship with others, but is himself alone. Macbeth is not without feelings of sympathy, is accessible to pity, is even the dupe of his uxoriousness, and ranks the loss of friends and of his good name among the causes that have made him sick of life. He becomes more callous indeed as he plunges deeper in guilt, ‘direness is thus made familiar to his slaughterous thoughts,’ and he anticipates his wife in the boldness and bloodiness of his enterprises, who, for want of the same stimulus of action, is ‘troubled with thick-coming fancies,’ walks in her sleep, goes mad, and dies. Macbeth endeavours to escape from reflection on his crimes, by repelling their consequences, and banishes remorse for the past, by meditating future mischief. This is not the principle of Richard’s cruelty, which resembles the cold malignity of a fiend, rather than the frailty of human nature. Macbeth is goaded on by necessity; to Richard, blood is a pastime.—
