Yes, Othello is easily led by Iago who is highly manipulative and motivated to destroy him. He is determined to get revenge for being passed over for a promotion that was awarded to Cassio.   Othello is an insecure man, although he is a successful soldier, well-respected by others for his noble bravery.  However, when it comes to his wife, Desdemona, he is lacking in confidence.  Although Othello believes that she loves him, he is awestruck to understand why she chose him.

He is a Moor, a dark skinned man, who she chose from a wide range of suitors.   She has defied her father's wishes by marrying Othello.  

Iago preys on Othello's disbelief at his good fortune in marrying the beautiful Desdemona. Iago instigates insecurity in Othello by insinuating that his wife has been unfaithful.   Little by little Iago plants doubt that is easily believed by Othello.  Building jealousy in Othello over Desdemona and other men who find her attractive is easy to do.  The jealousy escalates into rage, blind raging anger. 

To clarify how easily Othello is manipulated and controlled by Iago, Othello kills the innocent Desdemona without ever giving her a chance to explain the unusual circumstances that looked like she was unfaithful to her husband.

Othello damns his wife finding her guilty of sins she did not commit.  Based on Iago's innuendo and some think circumstantial evidence that is misinterpreted.
