I know I'm jaded but even I think a video of a naked man being dismembered and clubbed with his severed limbs is pretty fxckin dark. The boner definitely made it weird, but the soul rending part was hearing his voice change from screaming in pain to a pitiful, delirious mumbling "no...no..." as they cut his second arm off and took most of the flesh along the side of his rib cage with it.
