Their two differentiating personalities juxtapose the theme of good and evil. Aron, being a kind soul, chose to only see the good in the world; he would always try to prevent fights from getting any worse and “ he was always relieved when his bother let the tension go” (Steinbeck 334). On the other hand, Cal was always the problem starter and loved to pick fights because he was always confident that he would win them. Steinbeck even claims that if Aron were to come across an anthill, he would “watch the complications of ant life” and Cal would “kick it to pieces” (Steinebeck 345). Cal was always looking for danger while Aron was always searching for safety. Also to compare the two’s emotions that contribute to character, Aron began to tear up whenever Abra described a funeral for a person whom Aron did not even know; however, “there were few things that could make [Cal] cry” (Steinbeck 333). This exemplifies the different pureness within the two characters which directly relate to their good and evil
