Reputation, reputation, reputation! Oh I have lost my reputation! I have lost the immortal part of myself, and what remains is bestial.

Cassio - Act II, Scene iii

After a drunken brawl with Roderigo, Cassio is stripped of his position. Without his rank, he feels like he is nothing. This sentiment is echoed by Othello, who is motivated to kill Desdemona because her affair has besmirched the reputation that he has worked so hard to craft. Both Cassio and Othello believe a man is nothing more than "bestial" without his good name.
