That's like saying it'd be paradise for a girl to get gang raped by guys because she's straight. *rolls eyes*
Not that I'm against it though. As soon as you go out of your way to harm someone else, you've lost the right to complain to whatever they do when retaliating.
I'm not sure what to think about any implied "extra" threat of gay rape, but I admit that, as I was already expecting some sort of horrible torture, the Operation Evil Fujoshi here did make me cackle a bit.
Don't see many people mentioning the karmic/poetic justice of this act. Since this guy was directly involved he more than likely did what he did knowing she was being sold to a brothel to get raped over and over again until the poison finally killed her. Normally I'm not a fan of the "gangbang of death" scenario, but this is just too damn fitting/justice boner material. Oddly enough I think this is the 3rd time I've seen this happen outside of a hentai. Funny how small the world is, especially when you have fucked up tastes.
