I'm basically asking if there is any fiction (probably thriller or science fiction) where a murderer decides based on some kind of vote or poll who he kills, or they can suggest victims etc. I remember seeing a movie where the killer had a website the police could not take down, the first victim was an animal. It doesn't have to be the public making a choice between two victims, fiction where the killer poses a yes or no choice is also an answer (not to the victim, of course). If you know of any fiction with a theme like this, please answer this question! It would be a tremendous help.
