the Jester
Legend
That's something that the individual campaign will need to address.
I can't really address the issue fully without risking violating board rules in about three different ways, but I think I can reference it by noting that in the second Narnia book Prince Caspian, the good dwarf drew a sharp distinction between eating a "bear" and eating a "talking bear" and that it would have never occurred to either the Dwarf or the children to eat a Calormen or a Telmarine. Whether or not you accept his distinction, this is an issue that has to be addressed within a games morality system. Is there a distinction, and if so what is the basis of the distinction and why. Obviously, this is an issue for which there are lots and lots of different takes in real world morality systems. There are equally many takes you can give to a fantasy world, and arguably they would be a good deal more complicated given the number of different sophont races and species in a typical fantasy world.
This is a great point.
Perhaps the whole difference between so-called good and evil races could, in some milieus, boil down to whether you eat sentient creatures.
