Shakespeare villain who says "I am not what I am" (4)

I believe the answer is:

iago

(Other definitions for iago that I've seen before include "stage villain" , "Othello's treacherous counsellor" , "villainous ensign" , "Othello's Ancient" , "villain in play" .)

I've seen this clue in The New York Times.
