Wat was Nagatos reasons for collecting all the tailed beast??
remember nagato spoke of using the demon statue as a bomb??
When?
i think nagato tried to collect the tailed beasts to create a weapon (gedo maso) and didn't know about the plan of tobi. He was manipulated by madara to collect them to complete the moon's eye plan without knowing that the tailed beast's force will be used for madara's plan but to use this power to bring "peace"
the manga stated he wanted to create a powerful weapon, give to a nation to kill millions of people so that the world would know true pain, so they can intern come to acknowledge the important of peace. tobi just wanted to allude the whole world into a infinite tsukiyomi with the help of jyubi, so it seems tobi was using nagato to collected the biju's and nagato was planning on using tobi's pimp up sharingan to control the biju when it was revived so he could use it as that weapon nagato spoke of.
see i knew i wasnt the only person who seen something about a weapon................ but my thing is does the statue have anything else to do with tobi's plan. because it was a summoning only nagato could use right?
