"A hero is a hero, but everyone loves a good villain."
I'm interested in how everyone feels about writing villains. What's your policy? Do you like writing villains with a backstory and complicated motivations for their actions, or are your bad guys evil for evil's sake? I've certainly heard enough arguments for either side to last a lifetime.
As for me, I don't subscribe exclusively to either school. I prefer my antagonists have depth and complexity to them, and those sorts of characters are fascinating to write for, but I can certainly see the fun in a character who levels towns for no reason other than for the hell of it.
Anyway, what's y'all's take?
