Itachi could have been the saviour.

even if he knew, how do you propose he beat obito??

we already seen obito get rid of the amaterasu flames with kamui ( its obvious, it was kamui)

nah don't think so.. must be took his arm off and regrow..

Plot prevented him.

I swear people are stupid, obito said if he didn't keep a few secrets from him he could have killed him, however obito never said he could kill itachi, the fact that itachi waited till after he died to for a move to be made plus was very cautions with everything he did proves that he was well aware that he could have been killed at any moment, i bet the only reason obtio didn't put itachi down is because itachi played a huge role in sasukes development(who he wanted)
