Your assumption that Paarth would dominate the world is quite a stretch no matter how you slice the gameplay/lore ratio.
I'm saying that if he really wanted to, which he doesn't, there wouldn't be much that could stop a dragon. I'm not saying he could without a doubt, but it certainly is a possibility.
He was just the biggest butt kisser
Evidence?
and thus got to be Alduin's right hand man during the height of the carnage. He's not a dominator on any level. He's a henchman.
Henchmen don't typically fight against their former command, in fact the reason Paarthurnax and others turned against Alduin was, depending on where you draw your sources from, was because Alduin began to go mad with power and claim he was a god.
There's nothing to indicate that Paarthurnax, or even any other dragon, is a loyal "henchman." In fact the contrary is stated when the Dragons begin to question Alduin when they hear of how powerful the Dragonborn is.
In this era, he's our henchman.
He really isn't, in fact based on the dialogue between the player and Paarthurnax it's clear that Paarthurnax is the teacher/mentor in the relationship and the Dovahkiin is the student.
If you aren't a vampire, you won't be around to see who he follows next. Good thing we dispatched the other two main antagonists.
Paarthurnax doesn't follow anybody, buddy. He's spent thousands of years in seclusion trying to suppress his evil nature. The only contact he had with others being the Greybeards and Numinex.
There's nothing to indicate he is a follower and a henchman. Period.
Maybe you are putting Paarth on too much of a pedestal. He's nothing special.
According to Nordic legend he was sent by Kyne to help defeat Alduin. Through his teachings he's saved humanity twice. That's a pretty high pedestal.
He's no World Eater. He's just a simple henchman who hid away long enough to get old and wise and can be bent to give up secrets. I say kill him and put him out of his misery.
Opinions.
