There is enough wickedness in the world already. The only villain I feel comfortable bringing to life on my pages is the disillusioned hero who will become good again at the end...but will readers go for it?
But hang on...I just read the first two like this is a set of instructions. Like, "Kill someone, and record how it goes wrong." I suppose committing murder irl would be good writing reference. And I bet you I could also finish my novel, what with the twENTY YEARS IN JAIL I'D GET sweet Elbereth that sounds like a great idea. /Why don't I go kill someone and see how it goes wrong?/
