In Victor Hugo's "Les Misérables," the quote underscores the idea that the roots of wrongdoing often lie in the circumstances and environments that lead to such behavior, rather than the individuals who commit the acts themselves. It prompts readers to consider the larger societal and structural issues that contribute to moral failings. By identifying the source of these shadows, we can reflect on the responsibility of society in shaping individuals and their choices.

This perspective encourages a compassionate approach to those who engage in wrongful acts. Instead of casting judgment solely on the sinner, the focus should shift towards understanding the influences that led to those actions. This emphasis on teaching and addressing the underlying causes can empower individuals to learn from their mistakes and foster a more just society. In essence, to help those who err, we must first look at the context in which they operate.
