What makes a good villain for writing?
Some of you may think I'm contridicting myself with the title of this thread. "What makes a good villain?" Now, I don't mean what makes a villain "good", as that is not the purpose a villain. :D I mean is what makes a good villain "evil" and acceptable in a story?
My opinion is a villain that is pretty much pure evil, such as Lord Voldemort, Morgoth, Sauron, The Dark One (wheel of time), Torak (Belgariad), Darth Vader, Palpatine (Darth Sidious) and the likes of those.
Why? Because they strike fear into your heart at their menacing and evil appearance, and because they don't have any remorse or pity. They are the embodiment of evil, the heart of the dark.
That's the sort of villain I aim to create in my epic fantasy series (more info in the "Progress" thread, coming soon)
What about the rest of you, what sort of villains do you include in your writing?
