Re: manga 444
Konoha ninjas attacked and killed nagato's parents, that's why he said something like "this is how my parents were killed in front of my eyes by konoha ninjas" when he stabbed hinata back at chapter 437. Kishi is trying to show us that they did this by accident and that nagato's point of view and hatred is wrong... which isn't very convincing at all. All he lost was in the war, that's why he wants to prevent wars from happening so hard.
The problem is that now on, the manga is so easy to be predicted... it's sad, but after chapter 440, the manga became so predictable and boring. Hope kishi stop drinking sake and work back to give us a good plot like he did at kakashi vs pain and hinata confession... so we can have good predictions again.
By the way, this is what will happen in the manga next chapter (I believe it's so predictable that it doesn't even need a spoiler tag...
Nagato will tell the 2nd motive of his pain, the manga will ends with naruto thinking up and raising his head up "I know the answer!".
