Zamasu is shown to be a very calm and methodical person, as shown in combat when carefully perceiving his opponent's attack style and seamlessly countering in a fluid manner. While a man who cares for the development and prosperity of the universe, Zamasu often questioned the worth of mortals, not trusting in their ability to handle conflict as they were prone to commence war in a repeated cycle and not understanding that mortal life was key to the prosperity of the universe.
