Killing isn't the same as winning, dying isn't the same as losing. I could kick the crap out of someone and having them beaten to the ground, I could then get stabbed when I turned my back, I still won the actual fight. even if I died, he still lost the fight even if he killed me. Conversely judges and refs can name a victor even if the two fighters are still able to continue fighting. It isn't as simple as living and dying, black or white.
