Re: Official Tobi ID thread:All Tobi theories go here:-
"Hi, I'm Setsuna Uchiha, my son was killed, so I hatched an elaborate plan to kidnap 9 Deities and seal them within myself to rule the world."
No.:sy:
Sigh no, that's not how it goes, Setsuna already wanted to overthrow the leaf, and make uchiha the ruling clan of the world, but then his planned failed adn he lost support, then he continued to plan and form the akatsuki and following the death of his son he launched a solo attack.
Btw there is this thing called the principle of charity, if an argument sounds too far fetched and stupid you probably misunderstood it, and you should go for the least far fetched option.
His massacre of the uchiha clan was probably to prevent uchiha with the level of talent and skill as Shisui from rising up to fight him, or other uchiha activating the mangekyo, also it was probably partly for revenge, he would kill them and possibly reform the clan as the ruling clan of the shinobi world or simply take over the world himself as one single uchiha, either way the uchiha would have some form of glory.
It is also entirely possible for a man who has lost his son to hate the world, and if he has the means to destroy the world and his anger is not eased he may very well do so.
