What is the worst possible ending for Naruto?

Question though: What happened to Kabuto?

First I was thinking about composite Kabuto already attacking everything when Naruto comes back from the future, but then I thought its already bad enough when he gets some "one chapter Hanzo treatment" by the Uchiha-Bro's.

worst possible ending ofcourse is ; naruto uses talk-no-jutsu to convert tobi right away ,they hug , tobi apologizes to everyone , people forgive him , they hug ,hold hands and sing kumbaya while naruto and sasuke dance in the middle ~the end

At this point... though I use to be a strong advocate of the theory... would be if Tobi is indeed Obito... I mean why even flesh that out any longer...
