Final answer:
According to Darrow, he and Cassius are made of fire and ice, which symbolizes the contrasting traits and characteristics of the two characters in Shakespeare's play Julius Caesar.
Step-by-step explanation:
According to Darrow, he and Cassius are made of fire and ice. In Shakespeare's play Julius Caesar, Cassius tells Brutus, "Men at sometime were masters of their fates. The fault, dear Brutus, is not in our stars but in ourselves, that we are underlings." This quote suggests that Cassius believes that one's destiny is determined by their own actions and choices, rather than being pre-determined by the alignment of the stars.
