I think it's all of us. All humans, and all other conscious animals. Yes, even the criminals that rape and murder. And many oppose that idea, and I totally understand why. But if behaviour is dictated by brain structure, as the overwhelming majority of evidence suggests that it is, then even criminals are merely victims of their biology. That doesn't make those horrors ok, but under this view, they become just extra atrocities of nature, rather than any kind of 'free choice' made by a 'free agent'. If it has a nervous system, it can probably suffer, and therefore I argue, it is a victim (of nature/reality).
