Reach.I'm not sure about the "it'd be in Oscar's nature to end on a fight like this" part. There are better fighters than Mora out there, and win or lose, Oscar has never shied away from challenges.
Pernell Whitaker, Ike Quartey, Oba Carr, Felix Trinidad, Shane Mosley twice, Bernard Hopkins, and Floyd Mayweather. That's not a list of guys you fight if you're looking for the easy way through a career.
