I'm really, really torn about this point in the game. I've decided to go collect all the Dragon Priest masks in the mean time while I decide what to do. The arguments for both sides are just so alluring, kudos to Bethesda, I haven't been this torn in a game in DA: O! To some extent I think people need to look more closely as to the reasons provided for why Paarthurnax should be killed, because they're there just not obvious unless you pay attention. First and foremost, Paarthurnax's name in Dragon-Language translates too "Ambition Overlord Cruelty". He even states that you can't trust a Dov, so to accept blindly that all he'll do is try to teach the Dragons to be peaceful is skeptical. While yes, he did live peacefully on a mountain for a couple thousand years and left the world well enough alone, if he's going to be out in the world teaching and training other dragons, there's no reason to suspect that his "internal tendencies" won't revert themselves. His ideals and beliefs in the Way of the Voice are noble but I'm afraid I don't seem them as all that practical. Put a big enough hammer in someone's hand and they will inevitably smash something with it. His comments on the ending cutscene (which I cheated a bit and looked at on youtube) I also thought was suspicious, since he seemed very intent on forcing the Dragons to listen to what he says. On the flip side, he equips the player with the very weapon that can kill his far more powerful brother. If he had any intent on taking over the Dovah reintroducing the anti-Dragon weapon of doom is a big nail in his boney foot. He refuses to accept the Greybeards as his personal slaves (which he states they would be happy to do anyway). He fights against Aulduin when they player sees him on the mountain top. The proof of his good nature is certainly there. As far as the blades go, 200 years of no real purpose is long enough to bring change. It can be safe to say that the blades of TES: V are vasely different from previous games. It's only natural for change to occur, and I'm not sure I really want to support a group of warmongers, no matter how justifiable they can be. They should redirect their focus toward thwarting the Thalmor in Skyrim. (also, who the flying dovah does Delphine think she is for trying to order me around? :P Everything she says sets me up to be the leader of the Blades.) Side note, the biggest flaw in this game for me (aside from the Follower system) is that the Blades aren't very fleshed out. From the moment I met Delphine I was fully expecting a "Rebuild the Blades and Eventually Lead them Quest", not give them three followers and go kill some dragons (which you run into waaaaaay too often imho).
