Dear Iago,
You are a very wise and educated man; I’m convinced you have a very cunning and well thought out plan for you to undertake over Othello. To ruin his life, his status, everything associated with him you want to destroy, but do you really want that to happen? Othello has ever so much faith and trust in you that I’m certain he has told you some of his deepest secrets, to turn against him, isn’t that risky? I understand you are aggravated at Othello as he promoted Michael Cassio as lieutenant perhaps due to nepotism, but trust me trying to then destroy his life is not a judicious decision.
