What motivates Mr. Curtain in his quest for control?

Mr. Curtain is primarily motivated by his desire for power and authority over others. Throughout the narrative, readers can see that his actions are driven by the need to manipulate and control people to achieve his own goals. He seeks to dominate not only individuals but also society at large, using his intellect and resources to create an environment where he can dictate the terms of engagement. This lust for power reflects his overarching ambition to build a world where he reigns supreme, often at the expense of others' freedom and well-being.

The other motivations presented do not accurately capture Mr. Curtain's primary driving force. While financial stability and wealth may play a role in his plans, they are not his ultimate aim; instead, they serve as tools to further his quest for authority. Similarly, while a search for knowledge and truth might interest a person with noble intentions, Curtain's quest is less about genuine understanding and more about maintaining control. Revenge may be a theme in the story, but it is not the central motivation that guides his actions; rather, it’s his overwhelming need for dominance that defines him.
