Pacquiao The Merciful.. he didnt KO Rios out of compassion

[p4pking]

I thought that was the case actually. Whether Rios might have survived anyways, they did touch gloves several times during the 12th and it looked like a little agreement to ride it out. Manny was reluctant to sit down on his punches the whole fight, but Rios was really there to be taken out by the end and seemed to know it. Don't think it speaks one way or another for Pacquiao, he's done it before and he'll always fight with fire when he has to.

I noticed the reluctance to go for the stoppage, probably because of the killed KO he suffered.

But hey, Floyd doesn't knock people out either.
