You are right in that most people know nothing about it and b!tching about a societal ignorance is fair game, but complaining that people don't always write psychologically accurate characters is a bit like complaining that Pikachu isn't biologically viable. 

When you say generic psychotic monster, I think you're hitting the nail on the head with the word monster. These characters are destructive to the world around them in a way that reminds me of slasher movie monster/villain - they are armed with the designated role of villain that both automatically justifies their violence (in an RP, this may be social violence rather than literal) and makes a contract with the audience that they will perform with that violence in ways that allow them to be just slightly more powerful than their victims. When you go see Hallowe'en, you expect Michael Meyers to do some stab-stab-stabbing.

For me, what makes this fail as a concept is that the 'villain character' is usually the player's input. In those works where you can get away with having an almost two-dimensionally psychotic (forgive the use of the word; you know what I mean) character, the character is basically a plot device to give the real characters something to overcome or be destroyed by. Unless an RP has been founded around that antagonist (or had the antagonist tied into it), the antagonist has no role; the conflict is already there. Therefore, the antagonist's primary role reduced to being pointlessly belligerent in a way that typically seems out of place and usually obnoxious. 

The great and massively under-celebrated thing about RPing is that it's one story told from every character's perspective. Because of this, a character (like the antagonistic-by-design ones) that is not deep or developed feels egregiously empty. With all the space there for exploration, why isn't there any?

I don't think it's that a 'generic antagonist' is a bad thing by design: I just feel they typically feel out of place in RPs.

[b]Also:[/b] I recommend the British series Utopia to you. It's full of people getting slightly too comfortable with fighting against a government conspiracy and being able to break into houses, torture and kill people. That and the colours and soundtrack are beguilingly bizarre as well. The plot's a kind of generic government conspiracy one, but it's done with aplomb.
