What to do if all attempts by humanity to live peacefully lead nowhere? Right! Select four guards from the total number of people, isolate them and give them access to nuclear weapons.

What if, after 14 years, he realizes that he secretly hates humanity and doubts that humans are a species worthy of existence? After years of muddling your thoughts and poisoning your mind, loneliness can turn from a protector into humanity's greatest threat.
