In John Steinbeck's novel "East of Eden," the concept of inherent evil is explored through the idea that some individuals are born with a predisposition toward darkness. The quote, "I believe there are monsters born in the world to human parents," suggests that certain people may inherently possess malevolent traits, which leads to the notion that humanity is capable of great good as well as profound evil. Steinbeck examines the moral struggles and the choices that define humanity throughout generations.

This exploration raises questions about free will and determinism. While the characters in "East of Eden" grapple with their identities and the legacies handed down to them, they also confront the potential for redemption and change. Steinbeck's narrative invites readers to reflect on the complexities of human nature and the moral decisions that shape individual destinies, emphasizing the ongoing battle between good and evil within each person.
