Sasuke is literally Indra incarnate. His chakra and ashuras was passed down to sasuke and Naruto. No chakra, no body. Indra is dead, the only way he is alive is thru sasuke who he chose as the next successor. Hagoromo stated himself that ashura chose Naruto, so Indra must've chosen sasuke. Now why would he hate sasuke so much if he chose him to be his successor? Plus, Indra has no connection to itachi nor did he know him. /Thread
