I've been wondering why Sasuke would allow himself to follow the Sound and all, and at first, it seemed pretty obvious. "I am an avenger," he states, and his goal is to gain more power. Naturally, that has to be it, right?

But then I looked at something Kakashi said, that if Sasuke gives in to the Cursed Seal, that will be the limit of his growth.

So with this, I believe that Sasuke isn't going for the Cursed Seal level 2 JUST to gain its powers. Instead, his goal is to receive it, then DEFEAT it, just has he had been able to supress his Cursed Seal before. He wants to gain power from being able to control his cursed seal even when it's that powerful.

That is how he will gain power.

Anyone else got thoughts on this?
