Great chapter... awesome... amazing... etc. We get to see Pein`s feeling (or lack of). It was cool when he said something like "That`s how I lost my parents. They were killed right in front of my eyes by Konoha ninjas".
For fu.. sake, Nagato is strong... and disturbed

but he said that his pain is greater than Naruto`s and I believe him. He is right about that peace thingy, in some way. Naruto is just a kid, he can` do a thing. He doesn`t even realize the situation in the World of Ninjas. He`s still too young.
Now that the Kyuubi is out, Pein needs to retreat... he already used up so much chakra that it`s just incredible how he can still use any technique.
But what will happen to Naruto when Pein retreats? How will he return to "normal mode"? It will be Yamato time, I guess...
