If a website promised to execute someone that earns enough votes, how would that effect the world?

More importantly, what would the moral status of such a system be. Could it be a purely altruistic means of achieving justice when other methods fall short? Or is it destined to be a despotic means of extortion and bullying, becoming the evil it was made to destroy?

This novel explores these moral implications along with many other themes as the story traces the inception, creation, implementation, and ultimate destiny of such a system.
