Well with last chapter we're proven that his brother didn't got any juubi chakra.
So what after SO6P sealed the juubi into himself his brother got jealous and made indra go bad? or at least disagree with his ideals and his younger brother's ideals?
Maybe he was that made ninjutsu and the one to write the uchiha tablet,
There's so many possibilities that his brother could have done if he went into a jealous mode because his brother got the juubi.
