Well so, after he learns that Konoha is the reason why his entire family was massacred and that there was no attempt to improve conditions for the Uchiha clan to avoid a coup d’état (if you read the Itachi light novels you learn that Danzo actively sabotages Shisui’s attempt to influence Fugaku into stopping the plan for the coup), he forms a band of anarchists based on who he got to meet through his time with Orochimaru and partner with the Akatsuki with plans of overthrowing the leaf village and all the ninja governments since he sees them as responsible for the conditions of ninjas who are oppressed. He holds onto this plan all the way to the end of Shippuden, resulting in the fight between him and Naruto, who wants to maintain the order of the shinobi world and simply reform it from the inside through improvements to leadership. By failing to overpower Naruto he recognizes he does not have enough power to achieve the change he wants to make so he settles to work alongside Naruto and bide his time. In Boruto, I get the impression he cautiously trains Boruto and shows him the values of anarchy to see if perhaps he can convince him as a mentor to pick up steam for a revolution.
