I'm sure he will still work decently hard but not as hard as he would if the demon chakra showed itself and he had to rely on it. And what your saying doesn't make a whole lot of sense...And what your saying doesn't make a whole lot of sense...the only time Naruto had to worry about the fox is when he loses all of his chakra...If he's able to defeat pein (one of the strongest ninjas, if not the strongest) then what makes you think that he will continue training as hard as he has in the past? I mean so far he has defeated 4 bodies and 1 of the bodies twice pretty easily and obviously has a trick up his sleeve with at least 1 missing shadow clone. If he really defeats Pein with 3 Sage mode types all by himself then he would DESTROY anyone else that got in his way and it wouldn't make things as interesting.
