Villains - What they are? What they want?

Part 1:
Not all stories have archetypal villain bad guys.  Some just have a character or characters who are little more selfish, a little more powerful than your main character.

Some just have a character or characters who are a little more selfless, a little less powerful than your main character.

Not all villains want to take over the world.  Some just want to take over your main characters world.  Some just want to pull your main character out of their world.

Part 2:
The antagonist competes for the same relationship your main character is trying to achieve.  They may be many years apart in age, of a different sex, race, etc. but inside they want the same thing.

For instance, in the shawshank redemption - Andy and Warden Norton both want to have a relationship with "the State."

In Jaws, Chief Brody and the Mayor both want to have a relationship with "The Towns People"
