To understand why your character is driven toward a certain goal, get to know their positive and negative traits, as well as any significant emotional wounds that might be motivating them. Then you can explore the various kinds of conflict that could block them as they move toward their goal.
Enslaving a group of people Making others dependent on the character for survival Kidnapping, abducting, or invading a home Terrorism that utilizes hostages Cyberterrorism (information being held hostage) Taking over a city in battle Kidnapping or seizing a group of people against their will Forcibly confining others Having political power over the fate of others Having control over a group's mortality (life and death decision-making) Financially controlling others (family members, a town, a fiefdom, etc.) Making decisions that affect the fate of others (soldiers in battle, wartime prisoners, hostages, family members who enjoy freedom and safety only if one wishes it, etc.)
HUMAN NEED DRIVING THE GOAL (INNER MOTIVATION):
There are five basic human needs that, when missing from a character's life, could motivate them to pursue this goal. The following needs are all possibilities, but only one of them should be the primary driver for any given character. For more information on the relationship between human needs and outer motivations, please see this Character Motivation tutorial.
Self-Actualization: A character who gets off at controlling the fate of others may only feel actualized when this level of domination is achieved.
Esteem and Recognition: When a character feels a profound level of self-doubt, they may seize control as a way to banish their own feelings of weakness and vulnerability.
Safety and Security: If there's a perception of danger, a character may try to control others to return to a safe status quo.
