Watching an attractive female behead/dismember another attractive female. Fatally wounding a chick, and then literally fuck the life out of her while watching her die. Seeing a chick get fucked with a sword. Watching a female watch the person she loves most die slowly after being tortured. Watch nuclear families get slowly tortured and killed one by one. Force attractive mothers to watch their babies burn, slowly. Torture/murder/rape of attractive females, in various orders. Consensual sex, in the missionary position, for the sole purpose of procreation.
There's too many of them to list, ad they're not really "dark", but the fantasy is basically being able to enjoy people at the absolute worst moments of their lives or any form of chaotic/gruesome yet arousing situation.
