 Othello never loved before, so he doesn't know the feeling, which leads to a man who is more than likely to become jealous. 
 At the back of the book, it says this book is about envy and jealousy, both very different. 
 Jealousy is an obsession, a consuming passion that can take complete control over someone and cause them to twist innocent words and actions. This is Othello. He was easily persuaded that his loving wife was cheating on him. 
 We envy people who have things we wish we had ourselves; this is Iago. He was consumed with this, he would destroy anything in his path to get what he wants.
