[ think all animals (cows, pigs, etc.), if they're going to be killed for meat, should be killed as quickly and painlessly as possible, because in this day and age we know animals feel pain. It's possible the Japanese fishermen don't know this, but I think it's worse for the person killing the animal (in a karmic sense) if theydo know the animal feels pain and don't do anything to lessen it. I believe that intentionally causing pain to another living being brings back bad karma.
