As most of us have said, I agree that an additional warning shouldn't be needed based on the origins description.
However, in defense of the redditers, I can see how people could be surprised at the outcome of some of their choices with the character. I also acknowledge that there are unforseen outcomes with most of your choices in game with any character, which is done purposefully.
For instance, in the gale's hand scene from pfh the selected dialog choice was "fantasize about hacking off the hand". And I'll only speak for myself and the PC (as he did react with shock), but I was fairly surprised when that 'fantasy' became reality. And I think that was the purpose of that particular scene in the pfh to set our expectations of options with that origin.
