If my wife and I set up a fantasy role playing game where I pretend to rape her it is not a crime. As far as the knuckleheads were concerned it was consensual. They were victims also. stupid moron victims, but still victims of a crime. Had they known different then I could see the argument, but they didn't.
I get what you are saying,I still would not go so far as to call them victims. That implies an innocence that they do not deserve. They came back a second night after she fired a gun at them the first night. At what point does someone with even a modicum of intelligence begin to think that perhaps she hasn't consented? I'm assuming they were both walking upright, since they showed up at her door, so clearly they had a bit more intelligence than an inanimate object.
Change the crime from rape to anything else, they still wouldn't be victims as far as I'm concerned. You can't be innocent of doing something that is against the law simply because someone tells you it's ok.
Also, in the reverse scenario you mentioned earlier where it was a woman who was duped in a similar fashion, she's would also not be a victim in my book.
