Kyuubi only said Sasuke's chakra is as SINISTER as Madara's, not as potent or anything.
And seriously, there was no mention of Sasuke having a final Susanoo, so please.
sasuke has final susanoo. i think you're referring to perfect susanoo, which i never said sasuke has. you are in denial if you think that a susanoo user can only manipulate body parts not the whole thing.
and it has been said multiple times that an uchiha's hatred is directly proportionate to they're power. madara was the strongest and sasuke has dark chakra just like his. not to mention it has only gotten darker, than it was in those days according to karin
True, my bad. I mixed it up with perfect Susanoo, sorry about this.
Well, I guess we just need to see current Sasuke's Susanoo's size.
But it still doesn't mean anything since Kakashi doesn't need to warp whole Susanoo, just the user.
As for the "hate and power" argument, it's invalid. Itachi didn't hate anyone and was one of the strongest of Uchiha.
