Cassius prefers not to have Caesar as king because he believes that Caesar is ambitious and power-hungry, and that he will become a tyrant if he is given too much power. In Act I, Scene 2 of Julius Caesar, Cassius says to Brutus, "Why, man, he doth bestride the narrow world / Like a Colossus, and we petty men / Walk under his huge legs and peep about / To find ourselves dishonourable graves" (lines 135-138). Cassius is suggesting that Caesar sees himself as superior to everyone else and that he is already acting like a king. Cassius also reminds Brutus of the time that Caesar was offered the crown three times and he refused it each time, but he still wanted the people to see him as a king. Cassius fears that if Caesar becomes king, he will become a tyrant who will abuse his power and oppress the people.
