they and all the other top teir devils are trying to use the power as as way to change the devil world into another human society but modern compared to where they are in some aspecs still in the myan kind of age were the top value blood but will still kill or disown people that follow their society as seen with Sirzechs wife as she was put under house arrest because her brother is part of the Brigade and working with Vali's grandfather. So you could say they are several steps behind humans in that the pure and power is the top as shown when Zekram said that he would support the next head in becoming a hier to a mous so that his younger half brother can take over as the clan leader as ghe didnt view him as part of the clan becasue he didnt have their power of destruction but his mother power over lions. he also said that the four devil kings are view as leaders but in name only though they have their own factions within the government most of the government is made up of his clan meaning he is leading them.
