Lee has played "Skyrim" for several years now and enjoys writing about it and her various Dovahkiin.
This is a theory I actually thought up some years ago. My experience with most video game fandoms is that they hate my theories, but I thought I'd share this nonetheless.
My theory is basically that the Dovahkiin is a divine being aka a literal piece of God. It is, therefore, supposed to be ironic that everyone in Skyrim pretty much treats the Dragonborn like trash and tries to kill her.
Dragons Are Pieces of Akatosh
The dragons are not the children of Akatosh but are pieces of Akatosh's divine being. Dragonborn, meanwhile, are mortals with the blood and the souls of dragons. So Dragonborn are pieces of Akatosh too, which is what makes them divine.
Each time the Dragonborn absorbs a soul, they are just forcing the dragon souls to rejoin with Akatosh, the oversoul, and when the Dragonborn dies, they will likely rejoin Akatosh themselves.
This is why the Dragonborn can "sell their soul" to multiple deadra. It's because no one can own a piece of Akatosh, so the deadra are really just foolish, thinking they can own the Dragonborn, who is literally a piece of God.
The Nords Are Both Right and Wrong
The Nords are right about Talos being a divine being, but they are wrong about him being a Nord, which is yet something else that makes Skyrim deliciously, hilariously ironic. The game was seriously all about irony, from the Nords (who bullied the Forsworn and took their land) complaining about invading elves bullying them and taking their land to the dark elves in Windhelm being treated like crap after they enslaved the Argonians(and continue to treat them like crap in Windhelm. Check out Suvaris Atheron's personal journal to see how she treats the dock workers).
Talos is indeed a divine being, just not in the sense that the Nords believe.
We know that Talos is a divine being because his blood was used to seal the Oblivion gates, but mortal Talos (Tiber Septim) was a not a Nord but a Breton.
I became convinced of this when I saw the Skyrim quest "The Ghost of Old Hroldan Inn." When the Dragonborn sleeps in Tiber Septim's bed, they are mistaken by the ghost there for Hjalti, which was Tiber Septim's original Breton name.
The Last Dragonborn is mistaken for Tiber Septim because they have the same soul. In essence, the Last Dragonborn and Tiber Septim are both fragments of Akatosh, sent to the world in mortal flesh.
Also, Tiber Septim likely did not even mantle a god, because he already was a god. His soul likely ascended to rejoin Akatosh. This is what makes "the eight became nine" utterly ridiculous (Akatosh was already one of the eight) and is probably the reason the developers chose a name that means "foolish" for Heimskr.
Further evidence of this lies in Durnehviir, a dragon who is tricked into the Soul Cairn in the Dawnguard DLC. He is not truly owned by the Ideal Masters and can be summoned to the world again by the Dragonborn because of this. He is not really owned but is simply trapped and forced to play guardian. He had to be tricked in the first place because it was the only way to "possess" his soul in any way, shape, or form.

The Dragons Are God Interfering
It's my belief that the dragons were Akatosh's attempt to rule over mortals and guide them in his widsom, only it backfired. When Akatosh became flesh, he became Alduin, a twisted and corrupt version of his true intentions. Thus, the only way to undo the damage was to send yet another piece of himself (the Last Dragonborn) to stop the first aspect of himself that he created.
This is where the endless line of "Dragonborns" began.
There are actually two types of Dragonborn in the Elder Scrolls. There are the ones who are merely born with dragon blood (Tiber Septim's line) and then there are the ones born with dragon blood and the soul of a dragon, meaning they came directly from Akatosh. Meaning they were purposely sent to do something.
We learn in the Dragonborn DLC that Miraak, the first Dragonborn, didn't do his job and decided it would be better to join with the dragons.
Honestly, after playing Skyrim for years, I . . . kind of can't blame him. Most people in the world of Elder Scrolls are straight-up unapologetic jerks. They treat the Dragonborn like crap, constantly insulting her, trying to kill her, and trying to rob her. How many players eventually go crazy and slaughter a town? I know I've wrecked the Thieves Guild and reloaded a few times over the years.
The people during Miraak's time probably treated him like the scum on their shoe, while the dragons were the only people who were nice to him, and the daedra stroked his ego. No wonder he went bad. The Last Dragonborn is basically written to be the same way, only they decide to do the right thing and go ahead and save the asshole-world anyway by stopping Alduin and ending the cycle.
Given all that, you can see how it's likely Miraak's rebellion is the entire reason the Last Dragonborn was sent by Akatosh.
The Dragonborn Can Wield Keening
Lastly, we have proof that the Dragonborn is divine with the disappearance of the dwemer (of all things).
It's long been believed that the dwemer bound themselves to Numidium, a divine being, in service. When Numidium was destroyed, the dwemer disappeared along with it (I mean, they had already disappeared when they bound themselves to the brass robot).
In Skyrim, after finishing the main questline for the mage's college, the Dragonborn can help Arniel Gane replicate the disappearance of the dwemer. During the course of the quest, they are able to wield Keening, a blade that no mortal should be able to wield without dying—or at least without a special glove. The Dragonborn is able to do this because she is a divine being, as the quest itself demonstrates.
The Dragonborn is the one who puts the ritual together and Arniel Gane is the one who completes it by waving Keening about until he suddenly disappears. The end result is that Arniel Gane binds himself in eternal service to the Dragonborn, who is a divine being. Once the quest is complete, she is able to summon his shade to aid her in battle at any time, and when she dies, he will likely disappear . . . just like the dwemer.
This quest is basically Bethesda answering the age-old question of how the dwemer disappeared: they bound themselves in service to their god. This is also why we have only ever seen shades of them aside from one dwemer who survived and avoided being bound.
In short, the Last Dragonborn is a divine being. It's been hinted at over and over. Following this logic, they might as well be worshiped the same as Tiber Septim.
Though we all know that will never happen.
