Wow really? a tentacle? If sasuke didn't do it then kisame or someone else would have.are you sure that madara let sasuke kill obito? i don't think so.
P.S. if sasuke not give hachibi tentacle to obito all bad things can be easily prevent
No sasuke = obito wins war gg to infinite tsukuyomi.And so should Naruto have allowed Sasuke to be killed when he became a criminal. Hypocrite
Trueeeeeee.Or they could have just destroyed the Rinnegan. Thy didn't have to kill Obito.
