In "Ender's Game" by Orson Scott Card, the character Ender Wiggin experiences a moment of emotional vulnerability while reflecting on his own nature. As he leans against the corridor wall, he feels overwhelmed and begins to cry, grappling with his identity and the darkness within him. This introspection reveals his deep fear of becoming like his older brother, Peter, known for his manipulative and ruthless behavior.

Ender's realization that without the controlling influence of his monitor, he might descend into the same traits he despises highlights the internal struggle between his sense of self and the potential for aggression. This moment underscores the central theme of the novel, examining the fine line between survival instincts and moral integrity. Ender's fear mirrors a broader exploration of the qualities that define humanity and the impact of upbringing on one's character.
