Dear storyteller, why do you write dark stories?

I am not a writer but I am a reader, a reader of dark stories. I read them almost exclusively (one in particular who has already been pushed out of this site). I am in awe of people who have the ability to transform their experiences or fantasies into a work of art for the world to see. I do not possess this talent but, thanks to talented writers like most of you here, I am able to live them vicariously. I applaud you all.
