Animals are always innocent of any complicity in their own suffering though, which is not always true of humans. And their suffering is usually many times worse - for every war torn village there are half-starved cattle and donkeys kept working by the constant use of violence, for every underprivileged estate there will be animals needing vets for whom no money is left after buying fags and booze, and for every human self-induced illness there are millions of animals tortured to death, for no meaningful reason, in labs trying to find things like a "cure" for obesity.
