Bestiality - Not really? I mean, the Greek, Norse, etc deities & their stories are part of our games.... And it's been implied by one of the players that their character - who can shape-change into animals - will occasionally head off into the woods to find a good time with the assorted wildlife. Presumably as wolf + wolf or whatever. No one ever asked for the details.
Bigotry - Absolutely.
You don't pack a Monster Manuals+ worth of radically different intelligent things into the world & expect everyone to have a Coke & a smile.
Cannibalism - Cannibalistic 1/2ling are a thing in the DS setting you know.....
As are rumors of what goes on in assorted far off jungles/islands/Evil lands. Most monsterous humanoid tribes such as orcs/goblins/gnolls/ogres/etc are known to eat people.
It's a contributing factor in:
Genocide! - Not at all uncommon with the villains. But I've found very few players over the years who'll object to wiping out goblin/orc/etc tribes. In fact some of them have referred to Genocide as Plan C.
Incest - The Greek, Norse, etc deities & their stories are part of our games.... And it crops up as a villain thing. You know, GoT.... I haven't seen it on the PC side though.
Molestation & Pedophilia - No.
Murder - Of course. There's people (& things) murdering & being murdered all over our games - NPCs, PCs, good guys, bad guys....
Necrophilia - Does it count if both parties are undead?? Or living + undead? Anyways, living + dead, like whatever the shapechanger mentioned above was up to, it's been implied for some villains & a few PCs over the years.
Rape - Most often left implied or noted in the background. As in, the invading hoard was raping & pillaging.
I've not had any PC as the perpetrator. Not even the evil ones.
There's been a few PCs who've been victims in their backstories. There's been a lot of 1/2orcs with this as their origin (stated or implied)....
And one of the players specifically asked for this to be a possibility of something that could be encountered at a party the PCs were attending at the beginning of the current campaign. Um, ok??.... I wasn't intending on that, but since it was a specific request I gave it one 1% entry on the random chart. {it didn't come up though}
Slavery - Absolutely.
It's very hard to free slaves, run the Slave Lords series, etc without it.
And I've played an LE Chevalier in PF who (essentially) owned a teifling slave. I had the leadership feat. The Tiefling was my cohort. The other players thought the tiefling was a slave. The reality was the tiefling was a criminal serving a set period of indentured servitude to my order. A fact that could be, and was, verified in play. But for all intents & purposes? As I was the last known member of my order? My PC had a tiefling slave.
Thievery - Absolutely.
Torture - Most often implied or noted in the background. Mostly a villain thing. Though I've seen plenty of players who've stated that their PCs torture the (captive) for info. Ok, like the shape-changer & the Necro, I don't really need the details. So make a intimidation check.....
BTW, you forgot blasphemy.
