Cassio uses his passion to demonstrate how much he values other people and things constantly throughout the play. For example, Cassio and Bianca's relationship shows his value of women. He sees women as things for him to use rather than people he can develop an emotional connection with. Although Bianca has romantic feelings for Cassio, he
only sees her as a mistress. Cassio exhibits this mindset when he asks Bianca to leave at the end of Act III. He’d rather have Bianca leave him than have Othello see him with her and doubt his loyalty and focus on assignments. He lacks the respect people look for from each other. Contrary to his value of women, Cassio ardently reacts and mourns the potential loss of his reputation after stabbing the governor.
Cassio: Reputation, reputation, reputation! Oh, I have lost my reputation! I have lost the immortal part of myself, and what remains is bestial. My reputation, Iago, my reputation!
Cassio speaks and cries with exaggeration over the loss of his respect and position in society.
Cassio is naive and inexperienced. His intelligence and his loyalty to Othello gains him a high position in the military. Cassio jokes with Iago and the men at the tavern, all whom he sees as colleagues, but fails to recognize how his promotion affects his relationship with the others,
