Dude, how would you know what Kishi wants? It would be a stupid move. Why would Kishi kill Sasuke, bring him back with major power ups, then kill him again. It would ruin the story, because if you pay attention to the story of Indra and Ashura then you would know that Kishi is really aiming to end the war between both brothers and their reincarnations. If Sasuke dies with his hatred then the same sh*t would repeat itself all over again and this series wouldn't have changed anything.
Dude, I know you are a Sasuke hater, but get your facts straight. Read the previous chapters again and you'll see. Naruto and Sasuke will bring peace and rule together this ending the war between Indra and Ashura.
