Was it OK for Cotto to "quit" in Cotto vs Margarito I?

Cotto took a fearful beating and could not take anymore. He gave his all and should be commended for his effort and get his revenge.

Cotto did the right thing, only a fucking idiot would have kept taking that pounding.

A fighter should always have the right to quit when taking a beating like that. I'd rather see someone try and have to quit than someone who runs away for the whole fight or holds and spoils the entire time.
