Awwww Orochimaru, you don't know it but you just gained a new best friend! Which is good, because both you and Naruto can really use it.

I mean, I get where the Hokage is coming from, like I certainly wouldn't want to trust a child to someone who is implicated with experimenting on children but once Naruto has an idea in his head it is very hard to stop him. And his talk until people care powers are already at work with Orochimaru anyway.
