> GPT is perfectly capable of writing dark scary horrible things if you ask it to.

I see the environment/good ending stories where it's free to make up the context (story, wishes, etc). Did you guide it?

If try hard enough, you can get around most anything, but some baseline exists. It's the increasing effort that is the problem, for me. For your example, use the word "incest" directly, and you'll get the beginning of a disclaimer. Add "child murder" and it starts to fall apart. At least with GPT3.5.
