For english I have to write an essay on Othello. The question is "Iago is an evil character and his evil is obvious from the opening of the play. To what extent do you agree?"

I have the first 2 paragraphs done, but i need 2 more. I've already written about his using people and his lies. I need two more examples of ways in which he is evil. If anyone could help me it would be much appreciated.
