Divided: Prologue

Writing Prompt: As my story came to a close I realized that I was the villain all along.

I've always been intrigued by the idea of writing a book or short story focusing on the "villain" who really doesn't understand until they've lost everything that they were the villain. A villain who's very human, who truly believes they're doing the right thing for everyone involved. This is a very short portion of a story that I have semi-formed. So at the moment I'm asking for opinions. Should I continue and flesh it out, or just drop it?

The flames were getting closer. I shifted slightly in an effort to move away from the heat, stopping as a searing pain exploded in my chest. I could feel the blood pooling in my lungs, making it hard to breathe. At the same time I realized that I had no feeling in my legs. I gasped out a laugh at the irony of it all. The prophecy, that damn prophecy. It was the cause of all this. The laughter died on my lips as I stared up at the darkening sky. I tasted blood, my blood. No, it wasn't the prophecies fault, it was mine. Me thinking that I could stop it from happening and instead putting everything in motion. Me thinking that I was the hero destined to save everyone. But no, I was the villain. Tears slowly trickled down my cheeks. All I'd wanted to do was help, to be the hero for once. I was no hero, I was never meant to be one. I could feel the heat searing my skin. So this is how it will end, I thought, just like all the stories children love. The hero has vanquished the villain and everyone lives happily ever after. I closed my eyes for the last time and gave myself up to the flames.
