In discussing "The Tragedy of Othello", scholars have long debated Iago's role—highlighting the complexity of his character and manipulativeness. Fred West contends that Shakespeare was not content with simply portraying another "stock" morality figure, and that he, like many dramatists, was particularly interested in the workings of the human mind. Thus, according to West, Iago, who sees nothing wrong with his own behaviour, is "an accurate portrait of a psychopath", who is "devoid of conscience, with no remorse". West believes that "Shakespeare had observed that there exist perfectly sane people in whom fellow-feeling of any kind is extremely weak while egoism is virtually absolute, and thus he made Iago".
