I am always curious to hear this, the inherently evil, not skin tone.
I find it hard to understand, unless one applies very specific modern day connections to societal infrastructure, information dissemination, etc. that people have a hard time with this.
Here are some specific examples:
- A culture can feel empowered to own slaves
- A culture can worship something that leads to morally repugnant outcomes
- A culture can believe their "race" is better than others
- A culture can subjugate a class of people or group of people within its own culture
- A culture can apply different rules for genders which leads to unfair outcomes
Note, I am not saying that everyone wants to see this in their D&D game. Many don't, and that is fine. But, to insist that an entire culture before the age of cameras and information dissemination; one with closed and secretive borders that harbors suspicion of all outsiders that are believed to be below them can't be primarily evil, or at least commit evil acts daily seems a stretch.
All of history is full of societies that have done these things. I imagine with a spider goddess actually showing up from time to time, it might even be more prevalent. Morals and norms change with each generation. And each time they do, the next generation asks: "How did those people do that?" It's normal. A hundred years from now they may look back at people eating bacon and pig farms and just think we were all monsters, not different than serial killers.
The point is, closed societies can do atrocious things. It doesn't mean they don't care about their child or worry when their father gets sick. It doesn't mean they can't have a pet cat or dog and enjoy the love it gives. It doesn't mean they are monsters all the time. It also doesn't mean there isn't a small branch that opposes one of their atrocities. But, it does mean they see their amoral act as normal, where outsiders may not.
I don't know. I just feel like people sometimes sequester the individual as being archetypical of a society, when in fact, it is anything but. Norms, morals, and mores exist, and they should exist in fantasy worldbuilding too. If people just want an individual or a branch different, then they can write them in, no problem.
