I feel bad for the bull, who is the most innocent victim in this matter. He didn’t choose what to do, really, or to be used for that.
I feel bad for the bullfighter, not only because he’s in pain, but because of the circumstances that may have led him to be in the wrong place at the wrong time. Maybe he felt a vain need for glory, in which case I pity the vanity, or maybe he needed to feed his family, in which case there’s more people to feel sorry for.
I feel sorry for the audience, who apparently have nothing better to do than watch a bull fight. I’m sorry that there’s a culture that thinks this is a worthy form of entertainment, and I feel sorry that they seem to be quite heartless.
Mostly, I feel sorry for us as a species, that we are still so darn barbaric.
