Alright girlies bear with me: the dragonborn from skyrim is (unintentionally) TMA coded.
Think about it. Early in the main story you awaken a part of yourself that has long laid dormant, you discover what you really are. It's intoxicating, but even from those who are broadly accepting of your new identity, there's a distance. They're not like you. They can't know what your new existence feels like.
Then, after stumbling through this new life largely on your own or with outsiders' advice for a while, you meet Paarthurnax. This is the first other person who understands what it's like, what it means to be you that you've had a chance to really talk to. He welcomes you and rejoices in "the pleasure of speech with one of [his] own kind." For the first time, you begin to develop a new sense of kinship and, with it, a new sense of self, unburdened by the world that does not understand.
Over the course of the story, you also work closely with the blades. They don't understand in the same way, but they seem like allies you can trust, at least. Together, you do great and heroic things.
Then, one day, the blades demand that you kill Paarthurnax. He's done awful things, they say. And besides that, he's a dragon, anyway. Not like he could ever have been truly trustworthy.
The blades might not understand this. Might not realize that your soul is just the same as Paarthurnax's. Maybe they do. Hard to say. What's clear is that they don't trust any dragon, not really. They're all, at best, just ticking time bombs fated to do terrible things, no matter who they are or what they choose.
Oh, but not you, of course. You're a good one. You aren't like them, not really. You're helpful, agreeable, and you don't even look like them. Meanwhile, your soul goes on being that of a dragon.
It can't really be such a zero sum game, though, right? Surely these people have come to care for you as you do for them by now, and can be reasoned with? All the good times, all the things you've done for them, all your shared triumphs.
If you refuse to kill Paarthurnax, they will immediately cast you out and never speak to you again.
