Because Demon King " seems to put power and evil above all else" and when Meliodas was in his prime as a Demon before meeting Elizabeth, whole Demon clan was scared shitless of his mercineless killing and power, and he was still young af. That's why he wants Meliodas to regress into former self and be the ruler of the clan who the father could be proud of.
