Correction, what if naruto was evil... I guess we forget bout menma, and that naruto is half demon, Or was because ya know kurama is gone. If I may suggest, create your own unique character, it seems like you have story telling down.
i got a idea how about what if naruto was a reaper or a soul taker he would gain there memories justsus chakra and if he died with a soul he wouldnt die he would lose a soul and if he runs out of souls and he dies hes dead forever
