What with all the talk no jutsu complaining for the most part in every instance kishi has done it right and only naruto and hashirama use it. Why everyone complained after it happened to nagato. Nagato wasnt a freaking hidan or a deidara he actually wanted peace he is the perfect type of villian to be tnj'd. Also its not as if he didnt have to die for his crimes. Also it happened before zabuza was pretty much a talk no jutsu victim but it wasnt as if he wasnt bested in battle first and again he still paid for his sins. Konan eventually paid for hers as well and their have been more villians who died as villians. Only tnj victims were Zabuza, Sasori, and nagato/konan thus far thats only 3 occasions.
So whats the beef if it happens to obito. Doesnt mean he wont die Sasuke will still kill him for killing his fam or madara will. If madara unleashes infinite tsukuyomi. How would they know how to break it only obito would know so if naruto would have to deal with madara next only obito would be able to guide him. Now tell me why would the tnj be so bad obito is still going to die.
