Yet here, there was suddenly a Zetsu that matched no description, showed powers it shouldn't have, and shouldn't even be alive. That's reason to be very cautious. In the end it had none of the really OP stuff so he should've just Rasengan'd it from the start, but it easily could've been the kind that absorbed Ninjutsu and whatnot.

It's that lack of information (And thus hesitation) that caused him to not really commit to the fight, whereas if he'd been like Naruto and just went 100% from the start, it wouldn't have been much of a match. Then again, if he'd been wrong, they would've been screwed really hard.
