1. None of us here at Narutopedia are writing the Boruto manga, and we are not privy to the plan that any of the authors have in place. There is absolutely no way we can know.

3. Probably for the same reason that Orochimaru is free in the first place; his role in ending the 4th Shinobi World War. And I'm sure Naruto is aware of experiments that he's conducting; if he didn't approve of any experiments Orochimaru was doing, he'd shut it down obviously.
