I simply don't believe societies where everyone is EEEVIIL all the time is feasible. It completely loses any sense of verisimilitude. Even evil societies in real life, like the confederacy, worked by applying a different moral standard to a person based on their race/gender, rather than all being baby-eating psychos.
There are some creatures in the DnD multiverse that I have ZERO problems with being "EEEVIIL" They are typically not "races." In 3e those species are alignment "Always Evil" whereas races are typically "Usually/Sometimes Evil." It is rare to see a race that is full ("always") evil. There are inherent shades of grey already worked in.
Also, I would be hesitant from calling any real life governmental or political organization evil. Their views sometimes
we* may associate as evil. But I think it is probably a step too far to say "confederates" are evil.
Now to counterpoint myself, do you enjoy games where you were to fight against confederates, or nazis? The reason for this is even though you can see them as people, they are the enemy and its good to know who you can just mow down. This can applied to essentially ALL video games to one extent or another. Applying the inverse to RPGs works, but it needs to work across a gaming group. Having one party member (or the DM) saying one thing when everyone else wants another won't work out for the odd-member.
All people, of any race, gender, etc are "evil" to some degree. They may not consciously recognize it, but everyone does something evil, like not giving to charity, not helping the jobless get jobs, abusing their bodies for pleasure, or wasting their lives on sex/religion/video games/reality TV when they could be focusing on improving humanity as whole and ending all suffering. We can't all be Jesus, but we can't all be Satan either.
Not giving to charity = not good, not evil = neutral (individual reasons or circumstances aside)
Not helping jobless get jobs = again neutral (barring circumstances or reasons)
Abusing bodies for pleasure = usually chaotic, not evil
Wasting lives on X = swing and a miss, any alignment can "waste their lives", it is still not "evil"
They could focus on improving humanity as a whole and ending suffering = lawful good (usually), sometimes neutral good.
A society that consists entirely of baby-eating psychos cannot exist for more than a few days before everyone kills each other. You need most of the population to be decent people that are oppressed by an oligarchy that treats each other mostly decently.
Who are these baby eating psychos? I mean except for demons or some such? Orcs or similar
races (to my experience) don't generally eat their
own babies.
And I don't get the "You need most of the population to be decent people that are oppressed by an oligarchy that treats each other mostly decently," in relation to the previous sentence. Why do we need this? How?
Societies that exist in moral shades of grey (or orange and blue) are often much more exciting to explore than societies where everyone is literally a baby-eating psycho.
Oh, they certainly CAN be. They are also much easier to screw up. Just like if you are able to successfully naviagate and use the nine point alignment system effectively then it is much more exciting to explore than a good-evil one, though obviously people have confusions and issues dealing with such a system. Especially difficult is to understand the basic underpinnings of a orange-blue scale.
For once I would like to see a society of orcs or snakemen with motivations beyond "kill/rape/maim/burn." Even Tolkien himself stated that orcs and half-orcs (uruk-hai) were evil only because Sauron had shaped their culture to promote that and used mass dominate to maintain it (e.g. the "great eye" is a metaphor for him being able to see through the eyes of his orc and human slaves/allies, not an an actual giant eyeball).
And what about mind flayers? Demons? Devils? Beholders? Even Drow?
Many times the races you are talking about (orcs, snakemen) are actively taught to be evil and as often punished for weakness (being good). It says so in the descriptions of these races. There are outliers, individual characters or even groups who can and do defy the norm. But as already pointed out you can do this as is and if you make EVERYTHING grey then you lose motivations.
The best thing about having an orange-blue scale is that you get to recategorize morality. The worst thing is that all creatures must fall into the new paradigm. That is all that exists already. The nine points exists to create conflict and to give deeper motivations than "he's evil, get him." That is the point. Even if you are using 4e's scale of LG-G-U-E-CE then you still have conflict and SHADES of evil. Devils (in both systems) are evil, very evil, but they are a very different kind of evil than demons who just want to eat your face/babies.
*We in North America/Europe, as standards of morality are FAR from universal.. even in North America/Europe.
