Judge the Future

I was bound to a trial system that could execute future criminals, until I was forced to livestream the killing of a saint on the charge that he would destroy an entire city in three months. When I became a public enemy, the system warned me: all data had been tampered with, and even my revenge was a designed experiment. What is even more frightening is that future civilization is screening "qualified humans" through the system, and failed judges are dying one after another. And I have to decide in the next trial whether the evil man in front of me is a devil who deserves to die, or an innocent person who has been implanted with a crime. If I make a wrong choice, I will become the executioner; if I give up the trial, the system will kill me immediately. If I make one wrong move, I will become the executioner; if I give up the trial, the system will kill me immediately.
