Cassius

In Act 1 we see that much of Cassius and his type of character. He is an ambitious determined person. We know this through his persistant tries to persuade Brutus into thinking getting rid of Caesar is best. He even changes the minds of 2 other noblemen. This also makes him untrustworthy for turning his back on the ruler of Rome. He is superstitious for believing that the thuderstorm is some sort of sign. He seems a bit jealous of Caesar, and thinks that Caesar should not be crowned ruler, comparing him to a girl and noting time when Caear needed help when drowning. All in all, Cassius is an ambitious, jealous, and peruading character.
