No......Marquez has known since Naseem Hamed was ducking him that boxing is corrupt. He's well become accustomed with living with the stink that is the politics of the sport. I'm certain Marquez sleeps just fine.
This same Pacquiao boxistically dominated MAB in their rematch. ....because of this, alot of boxing writers heading into the Pac-Marquez rematch felt that Pacquiao could either steamroll or outbox Marquez. The quotes from Nacho Beristain before the rematch had him saying, "If Pacquiao wants to fight Marquez like he did MAB, we welcome it. It will make it an easier night for Juan Manuel." Nacho went on to say that to him, the more reckless version of Pacquiao is a much more dangerous fighter.
Styles has alot to do with it. Marquez pocket counterpunching allows him to be able to dictate to Pacquiao what Marquez allows him to do. There is no mistaking that Marquez was the ring general in both their fights.
Great fight the better man clearly won that night and wasnt robbed from a judging error like the first fight.
