Argyle King
Legend
How can you be unsure? It says they're evil in their description. Either you play the game as written (which means you don't have to worry about morality) or you interpret it as real.
And if you pretend it's real, how do purely evil races survive? A completely evil race would name their offspring Spare Rations 1, Spare Rations 2, Spare Rations 3, ... Being evil, they would not just be selfish but go out of their way to hurt others, any other including their own offspring. So how can the race survive if infanticide is a requirement?
As I said before, a race cannot be purely evil. It can at most be extremely xenophobic but purely evil races cannot last.
And if they're not completely evil, you judge individuals by their deeds and not condemn entire populations by the actions of some or even most.
There are some real-world animals which function in a way which isn't far from the hypothetical culture you've outlined here.
Beyond that, my question about certainty of evilness is one that I pose in the context of how elements of contemporary real-world look at fictional worlds.
As said previously, Demons and Devils are said to be always evil, but there are examples of such beings finding redemption. What level of burden is there to prove that a being cannot possibly be redeemed before it's seen as acceptable to resort to baser violent means?
