Re: Why aren't the Hellfire Club corrupted?
It's the Hell Club. Not the Hellfire Club. And they are the ones who summoned the Sins to Haven, but that doesn't make them corrupted directly. Perhaps their sorcerous knowledge protects them. Who knows.
Right. I guess I have read too much X-Men.
They certainly do look very Hellraiser-esque.
Yes, they are definitely inspired by cenobites.
