I think that one role the DM has is to provide adversity for the players (doing so through his NPCs or environment). It's the adversity that allows the players to make meaningful choices.
I'm not sure what you're getting at by saying the villian predetermines his actions; the villian doesn't exist, so how could he?
The DM's role is to provide adversity and challenge, not become that adversary. Understanding this is detrimental to being a DM. It is not the DM against the party. If it were, then no DM should provide things like treasure, and technically, the every sessions should end in a tpk. Now, the DM can provide adversaries without being the adversary.
PCs think in real time, they have full control over what their characters do. DMS control NPCS with predetermined personalities and in most combat cases tactics. DMs can control a character without being the adversary themselves. When I control the red dragon, the red dragon's strategy in the combat is determined by a tactical pattern that is predetermined.
example: The party's rogue steals a green gem of life that the dragon wants. During the combat, the dragon fights the party. The Dragon knows the party has the gem and because he's smart he is going to take out the wizards and fighters first, partly because he doesn't know which one the rogue is nor that the rogue has the gem. The dm knows this. The dm sees this the whole time. Heck the rogue told the dm he was doing this. So if the dm were the true adversary, then the red dragon would immediately attack the rogue and take the gem back and not risk his life on the wizards and warriors.
That is the different between the DM being an adversary and the dM controlling adversaries. I had a conversation last night about this very subject where i was mentoring a dM who had a problem with a player whom could not figure out that the DM was not the enemy. At every point he could he'd dispute what the DM had to say, and in some cases would not believe the abilities of the DM.
Of course my advise was the boot the disruptive player for the sake of your other players. Just an example of how important it is for both players and dms to understand that the dm is not the enemy.
