The concept of madness presents a unique form of terror, primarily because it cannot be controlled or influenced by typical means such as threats or persuasion. This type of irrationality challenges societal norms and fears, highlighting the unpredictability and chaos that can arise from a deranged mind. In situations of madness, traditional methods of addressing conflict or discontent become ineffective, leaving individuals feeling powerless.

This notion, expressed in Joseph Conrad's "The Secret Agent," underscores the fundamental struggle against forces that defy reason. The inability to negotiate or placate madness escalates the sense of danger and helplessness, emphasizing a deeper psychological exploration of human behavior. Confronting such madness can lead to dire consequences, making it a significant theme in the narrative.
