Even in Eberron, the "Shades of Grey" setting, you got "This is a good god" and "This is a bad god".
True, but it is a bit more flexible in Eberron than other settings. Because good people can worship elements of evil gods and evil people can worship elements of good gods.
"I'm a person who feels the pain of the injured, the downtrodden, the weak! I give thanks to The Fury for the passion of my feelings!" (ie: A CG person worshiping a NE goddess.)
"I'm a person who believes in my community and the links we have forged together. I will also messily and horrifically murder anyone who even speaks out against those I consider my friends. It's Us against Them. I worship Boldrei, goddess of the community." (A LE person worshiping a NG goddess.)
The best way to bring such things into the game world is for non-interventionist deities like in Eberron. I really like that about the setting. Moral ambiguity in the religions.
But if you must have walking-the-world deities, you can add colour to their religions by making the deities somewhat... vague... in their explanations of doctrine.
Cleric: I cast Commune. My deity, is doing
X a sin in your eyes?
Voice From Beyond: No.
Cleric: Is doing
Y a sin in your eyes?
Voice From Beyond: No.
Cleric: But this can't be!
X and
Y are in direct conflict with each other!
Voice From Beyond: It makes sense to me. Figure it out for yourself, mortal.
