In Richard Bachman's book "Rage," the quote "If you feel responsible for someone, you can finally hate him" points to the complexity of relationships and responsibility. It suggests that when people feel a strong sense of duty towards others, it can lead to negative emotions such as resentment and hatred. This emotional turmoil often arises from the pressures and expectations that come with caring for someone, highlighting the darker side of emotional bonds.

The quote serves as a reflection on the human experience, illustrating how love and responsibility can morph into feelings of animosity. It emphasizes the idea that the weight of responsibility can transform affection into anger when individuals feel overwhelmed, trapped, or let down. Overall, "Rage" delves into the intricate dynamics of emotional connections and the potential for conflict arising from deep-seated feelings.
