I hate to admit it, but I find it deeply satisfying when any of those professional animal torturers gets seriously injured.
Do not fall on the trap of "Hating in the name of love", that is definitely not a moral high ground.
Bullfighters have been getting injured for centuries, pretty much since the spectacle was invented. Like accidents during motor racing, nobody admits it but I believe it is even part of the show, in a very morbid way of course.
I do no think that bullfighting is moral or inmoral, but rather amoral. Death is a certainty for all living things, including that bull. And there is no way we can make that bull's death "morally acceptable". Please understand this sad fact: Animals cannot die peacefully of old age. First of all, that almost never happens in nature because old animals usually get eaten by predators, and big animals like the bull tend to have slow, painful deaths at the hands of their natural predators because they are simply too big to get killed swiftly. Actually we humans are probably the only predators that have developed methods fast enough to kill such large animals with little pain. The bullfighter is an exception in our modern world of cattle farms and slaughterhouses, like the natural predators of large animals, bullfighters infringe a slow painful death to the bull. Is it necessary? I think not, but then again the animal, iike all living things in this planet, will die someday.
And in second place, even if you let the bulls reach old age in a big ranch without any predators so that one day they die naturally, they will still suffer: The experience of ageing is also one of constant pain and fear for the animal. You cannot "explain" to a bull that he is getting old and he will die one day. All animals want to live on, they are hardwired to hang on to life as long as they can, but their bodies decay and the experience is, in my opinion, worst than a death brought by predators (or humans). So in short: Grandpa/grandma time, with medical care, supporting family members and eventual hospices where people die loaded with painkillers surrounded by loved ones is a modern human construction. Animals cannot experience this.
