>What I meant by evil gods being just like normal gods in ttrpgs is that in ttrpgs they aren't extremely dehumanized plot elements that exist to serve purely as antagonists.
Gods in TTRPGs are plot elements. How humanized they are/aren't varies. Most elements of TTRPGs are plot elements because they're based on folklore/myth/legends, which are first-and-foremost stories, with consistency being an afterthought.
>They don't even need to be the antagonists because you can worship them if you want.
They don't need to be in the idea that players don't need to actively engage them. They and their followers are very much often antagonistic towards the Neutral and Good deities of the FR universe and to Toril at large.
>> But in the forgotten realms setting there are entire kingdoms where worshiping evil gods is the norm.
You mean where worshiping Evil deities makes up a sizable minority/slim majority, and those kingdoms are in the minority when considering overall population. And they tend to not be very nice places to live, relatively speaking.
>> There is also the underdark, a huge place where there is very little good god worshiping being done. And then we have the multitude of evil humanoid races that worship evil gods and literally procreate like cockroaches.
You're trying to bring up the societies of Drow, Dueregar, Illithids, etc and their deities as examples of perfectly reasonable, decent, and rational that never fuck over members of their priesthoods?
>>Making Evil dudes act irrationally for the sake of being antagonists is too easy and is a boring concept.
Or, it can be giving the PC an excellent example of why it's a bad idea to follow evil deities. Sure, you get all this power now, but it has a price later.
You say that it's easy to see coming and obvious and nobody would fall for it, but PCs do fall for it every single day. And there's no end to their excuses about why dicking around with cosmic evil is justified.
