Obito wants to cast mugen tsukuyomi on the world because rin died no... He wants to do it because a friend he gave his life and eye for couldn't fullfill one promise because he's been in war and knows that the ninja world is fucked up..
He is actually just like nagato was his main drive was after yahiko was killed after they were betrayed... So i dnt see the big wow from memebers here we've seen this story before...
It was terrible during the Pain arc and it's terrible now. Wanting to cast the world into chaos or into a matrix knock off state because 1 person died is just ridiculous, specially in a verse where the highlighted profession has a high mortality rate.
Not only is that motivation lazy, but it's a cheap way to set up foil for Nardo when he starts spouting his TnJ BS, which we all know it's coming.
Forgive those who still had hopes that Kishi wouldn't go down that road again. Thankfully I'm not one of them lol.
