Antagonist

The Devil doesn't prevent you from getting what you want; instead, he corrupts your goal so it turns out uglier than you wanted, or he puts a price on it.

For example: Want to overthrow the oppressive government?
Price: You can assassinate the dictator, but it's a suicide mission, and your best friend, or your wife, is the one who'll have to do it. And you'll have to give the order.
Corrupted: You overthrow the Tsar but the Communists take over the Revolution and now you have an even more oppressive dictatorship, which you are responsible for.

Plot Layers

There's more than one plot going on at a time.

• Objective: what's happening as seen from the outside 
• Main character: what's happening from his point of view 
• Subjective: the main character's growth and self-discovery 

For example, in Star Wars:

• Objective plot: the Rebel Alliance retrieves the Death Star specs, loses Alderaan but blows up the Death Star 
• Main character: Luke starts as a farm boy and becomes a Rebel fighter pilot and hero 
• Subjective: Luke learns about the Force and embraces his heritage as a Jedi. 

The climax of Star Wars works in all three plots: “blow up Death Star” AND “become Rebel hero” AND “Turn off the targeting computer; use the Force, Luke”
