Obviously everything turned good at the end this is a shonen not some dark story. Outcome always turn good at the end in shonen : luck, TNJ, PU etc. Doesn't mean the initial decision wasn't stupid with the informations at hand.
Just wait for the green beast of Konoha return and wipe out Pain

Also, we all can agree that this was all just for build up between Naruto vs Pain... it was a destined match... and Naruto only came back when he mastered the Frog style and his training... so he did not cut short his training... in fact, he went to training there ONLY to fight Pain... so not coming back makes Zero sense to me
