Othello reaction.

"I am not sorry neither. I’d have thee live,
For in my sense ’tis happiness to die."

I feel sympathy for Othello. He has just killed his wife. She never cheated on him. In fact, she was faithful to the death. Iago, on the other hand, is despicable. He appears to be satisfied with others' death. I think part of them, though, could feel guilty. He refuses to admit his motivation. Usually, a sociopathic killer boasts about their clever manipulations and detailed methods of killing, when they are caught of course.
