In a dark way, Sasuke takes the same path as Naruto.
How did Naruto gain his control over the Kyubi?
It wasn't about training, he finally succeeds by being thrown in a pit by Jiraiya, by risking his life to force him to awake the power of the Kyubi.
Spoiler:
Naruto risked his life (well Jiraiya risked Naruto's life
) to obtain the power of his intern demon, Sasuke who seeks the kind of tremendous power that Naruto have, risked his life to obtain the power of Oro a demonic human.
