Oro isn't a god but then why hasn't Akatsuki killed him yet. This is what we know of about people who have left organizations:

1. Oro left Kohoha. All of Konoha nins know about Oro, and are to alert the third immediately. They are to confront and kill Oro.
2. Zambusa left the mist; Mist village sent hunter-nins for his head.
3. Sasuke left Konoha; Konoha sent a team (4 genins and 1 chunnin) after him.

Tsunade was fighting Oro without the ability of his arms. It was a handicap match and Jaraiya was there.
