one thing that came to my mind is this, what does danzo get in return if he is working for akatuski? what i was thinking is that danzo and pein might have had some kind of agreement before hand and pein would have said he would destroy konoha and danzo can recreate it however he likes and of course he will become hokage and pein will somehow get the nine tails, that might be his goal or something else. what do u guys think?
