In Victor Hugo's "Les Miserables," the concept of sin is described as a force that pulls individuals toward wrongdoing, much like gravity. This metaphor highlights the struggle between human nature and moral choices, emphasizing that, regardless of one's intentions, the tendency to stray from the path of righteousness is a powerful influence. Hugo's exploration of sin reflects the complexities of the human experience, where individuals often find themselves battling their own inclinations.

The gravity of sin serves as a reminder of the inherent flaws within humanity. Throughout the narrative, characters grapple with their own sins and the consequences of their actions, portraying a vivid picture of redemption and struggle. These themes underscore the notion that while sin may be an unavoidable aspect of life, the journey towards understanding and overcoming it is central to personal growth and spiritual redemption.
