Oded wouldn't stoop that low.  He's convinced he's better and even if Izzek won, Oded would convince himself that it was because Izzek cheated, rather than because he was better.<br/><br/>Of course if Izzek got jumped by somebody, Oded would be the first one to jump in to help, because even though he's just a dirty Zabrak, he's an Imperial asset and part of the team.
