It's purely arbitrary, if someone were to have an inclination towards a character because of their supposed legendary feats, they would continue to advocate their supremacy, deriving their arguments from misconstrued facts! We see this happening with the "God of Shinobi", Hiruzen, and also with Hashirama if you really look at it objectively! We've only been told of what they were capable of, and we base our arguments off of basically what Kishi says. And in some regards, it's better to leave up to the imagination what his intentions in regard to the development of certain characters are, because isn't that a pretty great element of plot called suspense? And besides, The Sage of the Six Paths hasn't been given any solid manga/anime action screen time, yet we still know him to be absurdly powerful!
