That's not it at all.
Somehow, I think you want too see Akatsuki succeed. Otherwise, all Akatsuki will die eventually, one after another. Unless Naruto is like OnePiece in this respect (we dont see any villain die) that would suck alot. So far, only a few villains in Naruto die, the sound five, Sasori....Oro should die, too
I seriously hate Hidan.
I feel his jutsu and way of fighting is somehow cheap.
And only having one move is weak.
But I don't think it's time to kill them both.
I want this series to last a long time, and killing yet another two Akatsuki would rush things.
They could get two new members of course, but I don't think that's gonna happen.
Tobi was there a few chapters befor Sasori died and is in my opinion exception.
Creating and introducing two new members into that strong group would not suit them.
And it comes down to Akatsuki not having the means to extract the kyuubi.
If they can't do that, their plan has failed.
And I feel it's still a bit too early for that.
Hidan should die by the hand of Shika, but Kishi can let Kazuku escape alive, and kill him off later on.
