The quote from Roald Dahl's "The BFG" reflects a grim observation about humanity. It highlights the uniqueness of human beings as creatures that can deliberately harm one another, unlike other animals that typically act primarily out of instinct or survival. This notion prompts a deeper reflection on the moral and ethical responsibilities that come with human consciousness and decision-making.

Dahl's work often intertwines whimsy with profound themes, prompting readers to consider the darker aspects of human nature. By stating that humans are the only animals that kill their own kind, he challenges us to confront the consequences of our actions and the potential for compassion versus violence within our species.
