Controlled.
It's hard to say exactly when the man once known as Akio Takamiya became dissatisfied with Konohagakure and its way of doing things; when he became so sincerely disenchanted with the life and death that had been laid out before him. As a young ninja he was well respected by his peers, sociable, charismatic, and handsome, these were words that were often used to describe him, traits that made him stand out among his fellows amidst a rather uneventful life and career, though they did nothing to reveal the doubts that grew in his heart.
One day for reasons even he did not know (and still does not), on the return trip from a mission, something snapped within him. Perhaps it was seeing his friends nearly die on that mission or perhaps it was just him being railroaded into a deadly situation by his village's need for money.
He told his friends and allies that he needed to stop off somewhere and take care of some personal business. Akio had never given anyone reason to question him before so they let him go only realizing their mistake when, hours, days, weeks later he still did not return. All evidence from the village's investigations pointed to Akio not being dead but rather a deserter, the village and his friends were wracked with the pangs of loss and betrayal and Akio was a wanderer.
Desperately seeking focus in his new liberated life Akio began to search for the future, first in deeds, then in contemplation, and then in the arts of divination all the while sinking into a debauched way of life with no morals or attachment though he yearned for both.
