Short horror stories

One shot

   Three friends woke up in a dark room. They had no memory of where they were and how they got there.
  The room was completely empty, except for a note and a gun.
  The note read; there are three friends and one gun with one bullet. One friend will have to die in order for the other two to live. It is your choice.
  The three friends were terrified. They had no idea what to do. They all cared about each other.
  They argued for hours, trying to figure out what to do. They looked for ways to escape, but there was no way to escape.
  They decided just to spin the gun. Whoever it would land on would have to be shot.
  Once the decision was made, the one friend grabbed the gun. He cried as he shot the bullet.
  Instead of shooting the bullet however, I gun had exploded and killed him. The other two were set free.
