- Totally ignore that Nagato exhausted chakra destroying Konoha
- Totally ignore that, yes, he was trying to capture Naruto, not kill him. If so, he could've soloed with a Chibaku Tensei right at the beginning
- Totally ignore that Pain could've brought Gedo Mazo with 7 Bijuu in it with him on his rampage.
