I think they kind of screwed up this quest.  Nobody is going to kill Paarthurnax.  The game hints at the idea that being power-hungry is so intrinsically tied to dragonhood that Paarthunax will inevitably turn bad, but they don't really flesh out that concept enough to make this choice difficult.

That's why I killed Delphine and stuffed her in a river. PC version.

I used to tell you what to do..then i took an arrow in the knee.

On my primary character, I let him live. Same reasons as everyone else, really: he's a pretty cool dude, and "Our oath requires that we kill him!" is a really stupid line of reasoning.

On another character, I was going for a "Blades" thing, and recruited a bunch of followers into the Blades. On him, I did kill him. I felt really bad afterwards, though. I don't like playing that character anymore, he feels dirty.

Yeah there is no way I would pick the blades over the dragon

i don't claim to be the best blacksmith in whiterun, all i ask is to give Paarthunax a fair chance.

Paarthunax is all about the love, baby.

When I got asked to do this by the Blades the fact that I couldn't convince them to change their minds despite the fact they were being dumb stubborn fucks, was pretty disappointing. Especially when they continue to hold their position after I saved the god damn world. Like hey guys I prevented the apocalypse so how bout you throw my pacifist dragon buddy a bone, you know consider it a favor to me or something.

Oh yeah remember that whole part where you blades were searching for a dragonborn for like 200 years so that they would actually have a purpose again, and yet you refuse to take any input from me? Well how bout fuck you two then. I'm going to go over here and hang out with these mountain shaking guys, because they happen to be a bunch of real motherfuckers.

Take that shit elsewhere. It hasn't even been a month and that stupid meme is already tired and unfunny.

Yeah, as soon as Delphine pretty much told me to fuck off unless I killed my little dragon mentor, I tried to kill her instead. Didn't work though.

I shouted her off the fucking mountain. It was really funny, because she fell a LONG way down, and took quite a while to disappear from sight.

Let me guess, someone stole your sweet-roll?

I made a new character -a supposedly evil one- to do everything that I could not do on my heroic one. When it came to kill the adorable dragon though I could not find it in me to do so. So instead I went to the Blades, shouted and fireballed their asses every time they tried to say things like "You are not welcome here if you havent...." baaaam and watched them shut up and crawl on the floor...felt good :))) This is what happens when you try to patronize the Dragornborn!

@AckbarTheGreat: thats like the best desciption for him.

That turn of events felt really cheap. I wish you could talk some sense into the Blades so at least you could do their quests.

But fuck that shit, Paarthurnax is probably one of the most compelling characters in the game, and is my homeboy.

All this reminds me of is the woman who sits next you in the "peace treaty" discussion. She literally had a comment for EVERYTHING anyone ever said, and completely threw away every fucking milligram of logic and reason whenever Ulfric so much as farted.  
 
First time in AWHILE that I wanted to strangle a character so bad. 

I killed him.

Yeah this basically sums up the whole situation for me. Its pretty fucking stupid that they built up this whole idea that the blades have been waiting for you all this time, and now that you are here they exile you because you won't do something they ask of you.

If you play on the PC, just use the console to skip ahead in the quest. You get to keep Paarthunax and be chill with the Blades.

The way parthunax is handled only adds to my disgust of this game.

Really wish I could kill Delphine!

Rek Bein Krah Dir, she is foul and cold, and needs to die!

I tried to kill Delphine and Esbern when they posed me with this quest, but the game did not allow it.

They really need to make it possible to kill Delphine and Esbern at the end of the game in Paarthunax's name.

I used to really like the Blades in Oblivion, now, they're just rubbish. They weren't strong enough to keep their Order up and running, so listening to them wouldn't be wise in this case.
