Prolly won't kill him but just keep him drugged/poisoned and use/test on him. Kabuto was waaay too intrigued that one of Oro's test subjects from soooo long ago turned out extremely successful. He'll definitely want to test on him.
They might take yamato cells and try to fuse it with someone , he is like the first hokage , and yamato might could control the Juubi since he has first hokage dna ?
idc who i just want someone to die what would make it even better is if they killed someone right in front of naruto, i wanna see what he gonna do then!
