Adam has twin sons, Cal and Aron.
They become the “Cain and Abel” throughout the story. As relating to Cain, Cal takes on his role, while Aron is Abel. Cal is jealous of his brother Aron because he is seemingly perfect. Cal does not directly kill Aron, but Aron gets killed because of Cal. Adam asks Cal where Aron has gone, and Cal’s response was, “Am I supposed to look out for him?” After murdering Abel, God questions Cain about where Abel is, and Cain answered, “Am I my brother’s keeper?” Steinbeck strays away from the biblical story because Cal tells Aron that their mother is still alive and is living as a prostitute. Hearing this destroys Aron causing him to enlist into the Army during World War 1. Aron dies in France. In the bible Cain physically kills his brother, and Cal indirectly kills him. God sent Cain to live in Nod, East of Eden and he cursed him. In the book, Cal realizes that he can overcome his sin, and he is forgiven by his
father. Charles loses his temper and cuts his head with the crowbar he was using. After the wound heals it leaves an ugly scar where the skin is darker than his skin. Steinbeck relates his scar to the “mark of Cain.” God banishes Cain to East of Eden and puts a mark on him causing no one to kill him. Steinbeck keeps it different because the scar is not really a curse, just a form of protection. John Steinbeck made many allusions to the bible; the most used allusion is Cain and Abel. He started by using Adam and Charles Trask as Cain and Abel, and by the end of the story it is Adams sons Cal and Aron. Steinbeck kept the stories closely related, but there were instances where he changed the story up, and made it his.
