Julius Caesar help! pleaseeeeee?

number 2) Brutus believes himself to be perfectly principled and constructs for himself a faulty self-image as the preserver of Roman democracy; as a result, he even sees his part in the ination as a noble cause. He is convinced that his friend, Julius Caesar, will be a tyrannical leader; therefore, to save Rome from a certain dictatorship, he decides Caesar must be destroyed. He willingly joins with the conspirators to accomplish his goal. His problem is that Brutus cannot realize that men like Cius, are inherently self-seeking by nature, for he has never been a selfish man or sought his own self-interests; therefore, he is easily duped and falls victim to the other conspirators, who use him for their own purposes.
