What Is Caesar's Opinion of Cassius?

Caesar recognizes Cassius's ambitious nature and the danger he potentially represents. Caesar acknowledges that Cassius is extraordinarily perceptive and observant, using his abilities to manipulate the people around him. However, Caesar fails to consider his own mortality and underestimates the depths of Cassius's resentment, ultimately leading to his assassination as orchestrated by Cassius.

Caesar's analysis of Cassius's nature is accurate and justified, but Mark Antony counters his harsh judgment by declaring Cassius "a noble Roman and well given," giving the audience insight into the general opinion of Cassius.

Initially, Cassius's worst traits are magnified, and he appears to lack scruples entirely, outright lying to Brutus to convince him to join the assassination plot. He also does not object to bribery, the selling of commissions or the raising of taxes to generate income, marking him as at least mildly corrupt. However, he is also characterized as intolerant toward tyranny of any kind, implying that his hatred of Caesar is driven by more than his personal ambitions. He is highly emotional as well but is not above using emotion as a powerful rhetorical tool. At the end of the play, he comes to value Brutus's friendship and refuses to turn on him, killing himself when he believes Brutus's army is defeated.
