Or he's simply one of those "letter of the law" types, and even if he's obviously an evil dick, Doflamingo is still the governmentally recognized ruler of this country still.

Hasn't he said he wished to abolish the whole shichibukai system? He certainly is a letter of the law type, who consider himself nothing but an insignificant tool of the law enforcement. That's why he obviously doesn't care for any compromises or treaties the world government might make with suspicious parties. Yet that should only push him to chase Flamingo down all the sooner. Unless, of course, he's actually thinking that the current situation would allow him to put down a whole mass of pirates or other criminals, seeing how they are all trapped inside Flamingo's cage. It would be not just a bit cold to treat all the citizens of the capital as unavoidable collateral damage, though.
Except he does care.
If he wasn't really a letter-of-the-law type, and he really wanted to get rid of the Warlords System, he'd just take out the Warlords himself.
I think it's obvious his intention is to use his influence as an Admiral to work within the system to get the World Government to repeal the Warlords System.
