Rin did still have the Sanbi inside of her, so going back to the village would lead to another tailed beast invasion. ;P
Now what if Itachi told Sasuke the revolt? Would Sasuke be able to change anything? Sasuke might not bear any hatred towards Itachi and seeked more power for revenge, and would not go to Orochimaru to train. He could perhaps even look for Itachi to train him. Who knows how the whole series would have changed.
