Yeah I know, but I always found it odd that Naruto and Bleach had big events at around the same time. The most memorable one for me was when Bleach had the Ichigo vs Grimmjow fight and the Naruto vs Deidara fight at the same time. Also in Naruto and Bleach they were both talking about the past in recent chapters.
I am sure there were other "coincidences".
In my eyes Nagato did what was necessary. Lately everyone has been talking about the cycle of revenge in Naruto. Pein killed anyone that might have had the notion of seeking revenge thus assuring the stability of the country. He sacrificed the few for the many.
