^not the power makes someone go crazy, the one who got the chakra was the second child (the on with the sages body) and he got depisted as "sane" person in the story even after getting So6ps power :I

the first uchiha got "crazy" because he wanted to be the one chosed by his father, jealous and whatnot ^_^
