Nope, we didn't get full god mode experience until he raped all of the captains at once then said he planned everything, having the enemies that could overtake SS in few numbers are MID LEVEL, possibly even high level.
Still works out the same, Itachi uses sparingly over a long time, Sasuke uses lots in short amount of time, hence the incredibly fast degeneration.
They both had the same views, even Naruto was confused and wanted to destroy and get revenge to gain them, hence the conflict he had, and releasing kyuubi, seeing that he could change things for the better Nagato was convinced, his ideals stayed the same, minus destroying everything to gain them.
Nope, he said he'd destroy Sasuke and take himself down too if he tried doing anything to Konoha, that's called development from the kid who wanted to chase him and hyperventilated, he certainly kept his cool then. And he didn't put the Hokage goal behind him, saving Konoha / saving teammates and being a strong leader is the whole concept of kage, he's working towards that.
So Madara is now a tailed beast's hatred? *rolleyes*
