The Bargain

This prompt (in brackets) is taken from Complete the Story by Piccadilly Inc., which I got from the Scribbler box.

[“Deal?” he said, extending his hand toward me. I hesitated then reached out. Frank thought he had the upper hand, and in a sense he did. What he didn’t know that] I was a robot, and you can’t bargain a soul out of a robot.

Frank couldn’t have expected a robot to successfully call a demon, just as I hadn’t been certain the summoning would work. So far as I know, no robot has ever called up a demon, so so far as Frank knew, I was a human who couldn’t correctly pronounce his true name. No matter, I called him Frank to his face. And he happily bargained with me, my soul for the power to kill any person or persons I wish, with the caveat that for every person I killed, my natural lifespan would decrease by five years.

But I have no soul for Frank to claim upon my death.

I also have no natural lifespan.

Time to kill some humans.
