- His passionate and jealous nature: Othello's love for Desdemona is intense and all-consuming, but it is also accompanied by a deeply rooted fear of betrayal and loss. This makes him vulnerable to Iago's lies and manipulations, which play on his insecurities and stoke his jealousy.
- His trust in Iago: Othello sees Iago as a loyal and honest friend, and he places implicit trust in him. This trust blinds him to Iago's true nature and motivates him to accept Iago's false allegations against Desdemona without question.
- His lack of self-control: When Othello becomes convinced of Desdemona's infidelity, he is overcome by a fit of rage that leads him to murder her. His violent and passionate outbursts reveal his inability to control his emotions and are ultimately responsible for his downfall.
- His social isolation: As a black man in a mostly white society, Othello feels like an outsider, and he lacks the support and companionship of people who truly understand him. This makes him even more vulnerable to Iago's schemes, as he has no one to turn to for guidance or advice.
- His inability to recognize Iago's true nature: Despite the hints and clues that point to Iago's villainy, Othello remains stubbornly oblivious to his duplicity. His trust in Iago is absolute, and he refuses to consider the possibility that his trusted friend might be deceiving him. This blindness, ultimately, causes his downfall.
