Hypothetically, if Mordekaiser won and the entirety of Runeterra is now under his domain, how would he rule?

I know he is a conquerer by nature, and that domination and cunning are kinda his MO, but if he achieved all his goals, you guys think he would actually try to give the citizens under his rule a good life? or would he be a dickhead?

I like to imagine that Mord would kinda go crazy if he had nothing to conquer, so he'd set his eyes to the celestial realm, or the void, or some other realm. Kind of always giving himself a goal that align with his tyrant ways.

But if he was satisfied with ruling all of life (and death) on Runeterra, I wonder if he will usher an age of peace and prosperity, or instead cultivate cruelty and injustice. Surely as a person accustomed to ruling, he would know that peace is the best way to choke out resistance?
