This is a great idea. But remember, finding per se symbolism in a render is not always easy. Many tortures in real history and fiction featured torturers who did not wear any clothing or symbology of holy orders. The torturer was often some creep who was paid or got off on it. I hope others would contribute to this thread where religion could be placed in the thought of the render.

Hypatia comes to mind, in that her murder was by religious nut jobs, and was totally guro in nature. Fucking HOT.

I hope you have success with this.
