I don't think the problem of Sasuke is from Indra.It is beyond Indra.It might have something to with the nature of chakra which influenced humans,especially the Uchiha clan and their father Indra.The Sage overlooked this possibly and instead gave humans.Madara Uchiha stated he would eliminate the evil chakra.Look at chp.665 for more info
