The quote from Victor Hugo's "Les Miserables," "Every blade has two edges; he who wounds with the one is wounded with the other," highlights the inherent duality of actions and their consequences. This suggests that harm inflicted upon others often leads to repercussions for the perpetrator, indicating a moral lesson about empathy and responsibility. The metaphor of a double-edged sword emphasizes that we are often affected by the very actions we take against others.

This idea resonates with the themes of justice and redemption present in "Les Miserables." Throughout the narrative, characters grapple with the consequences of their choices, illustrating that acts of violence and cruelty often return to the doer. Hugo's work urges readers to consider the interconnectedness of human experiences, emphasizing that hurting others can ultimately lead to one's own suffering, reinforcing the importance of compassion and understanding in our interactions.
