While it may be true that one of Belial's goals in establishing a council was to settle disputes peacefully, his ultimate objective was far grander and more self-serving.
Possessing a shrewd and calculating mind he saw an opportunity to solidify his position among the demons, to assert himself as a formidable Demon Lord capable of leading and making decisive decisions on the behalf of other demons.
Through his carefully crafted words and actions, he presented himself as the epitome of strength and leadership. He skillfully manipulated the circumstances, channelling the demons' collective fear and uncertainty towards himself, casting an aura of authority and stability around his persona.
