Psychology in Othello

       The character of Othello has serious psychological issues. The color of his skin makes him self conscious of everything about him; he thinks that Desdemona had some other extrinsic motive to marry him, not just for the love that she had for him. Therefore, he becomes extremely jealous of Desdemona. He thinks that Desdemona does not truly love him, and it's ironic because when Iago first suggests that Desdemona is sleeping with Cassio, Othello wants proof that they are sleeping together, rather than dismissing the idea altogether. His psyche is naturally jealous of everything, and so he just needs that little spark to put the jealousy in motion, and Iago gives that spark to him.
     He becomes so jealous to the point that he believes circumstantial evidence that he is a cuckold; he does not even have any actually proof that his wife is having an affair. Also, he does not confront Desdemona about anything; he just jumps to conclusions and assumes a lot of stuff that are not true. Iago's plan is working so perfectly that he has Desdemona constantly ask Othello to give Cassio's job back, so this only makes Othello more jealous because he realizes how badly Desdemona wants Cassio around all the time and that is for one reason only: that she is sleeping around with him. When Iago mentions the ridiculous story of how Cassio kissed him that one time on the lips and moaned Desdemona's name, Othello believes it because his jealousy blinds him to reality.
