1. Don't get it twisted. IM not talking about Nagato himself as clearly Nagato>Pain.
2. If 8 tails broke out of the first CT, how you so sure he couldn't break out a bigger one?
Also, even if he was to make it bigger, the full 9 tails would surely emerge.
3. Saying he had chakra to revive the village is a moot point. What happened after he revived the village? He DIED. What will happen if he would have attempted another even bigger CT? Death.
4. IM tired of hearing this "it was plot" bullshit. Everything is plot. Pain beating Kakashi was plot. Pain destroying the leaf village was plot. Pain defeating Jiraya was plot. Deal with it.
deva was about to make it bigger before naruto came out,even if the full nine tails came out,he would increase it again
he was prepared to die,he didnt mind,he however was casually about to make a bigger CT without any fear,so he wont have died
deva solo'd konoha,solo'd sm naruto+ma and pa+3 boss summons+6tk naruto,and was abt to solo 8tk,whether you like it or not,deva will solo base naruto very easily,unfact,animal path would even suffice
