In "The Storyteller," Jodi Picoult explores the psychological effects of repeatedly engaging in the same behavior, regardless of its morality. The narrative suggests that continuous repetition can lead individuals to justify their actions, even when those actions are inherently wrong. This concept reflects how humans rationalize their decisions, often bending ethical boundaries to accommodate their choices.

This idea underscores the complexity of human morality and the mental processes that allow individuals to avoid confronting the truth about their actions. By delving into this theme, Picoult encourages readers to consider the ways in which we can deceive ourselves, highlighting the dangers of normalizing unacceptable behaviors through cognitive dissonance.
