All in all a nice wrap up... Yea it's not exactly like the Kage are saints. Orochimaru has great power of knowledge that may be of great use. Besides, if he no longer uses citizens to experiment (and Shin seems to have taken care of that) and no longer desires to destroy Konoha, then most of his threat is gone. Same for Kabuto. So yes the Ninja world remains a world where rules are mostly pragmatic.
