If the Empire gets in a position where they effectively have veto power over any diplomacy or war that happens on the continent, then I'd say yes, it is absolutely their duty to try to create fun for others.
Sort of a "you bought it, now you have to manage it" type deal.
I have to agree. All rulers when they become ruler are informed quite clearly that they have a responsibility to ensure a fun environment for their players. If you become ruler of an entire continent you have an even greater responsibility.
