Well I disagree, I think Dany fundamentally has an altruistic streak, and a desire to help the downtrodden because she too was downtrodden once. She also has a ruthless and obsessive desire for a home, for the throne, and I do think these two qualities intersect at times such as in her brutal punishments and actions. But I do not think she did things like saving Mirri, freeing the slaves, etc, just because she has an addiction for adoration.
Also, there's never been any mention in the show that the cities in Essos have been reconquered. For all we know, Daario is still keeping things fine over there.
