Rebirth of the General Princess

A fire of conspiracy killed her and her mother. When she opened her eyes again, she was back to the time when she was ten years old. In this life, she no longer wants to be a kind person as her mother said. The purpose of her rebirth is only to protect the people she cares about most. Even if the dynasty is destroyed, even if her hands are stained with blood, and even if the people in the city die for her conspiracy, she will not be moved. However, how can God send such a man, who destroys him repeatedly but also helps him repeatedly? What should she do to him?
