Gunpoint

Evan stared at the gun in front of him, the long sleek barrel reflecting the sunlight in arcing glints. The hole was pointed at his face, a mere inch away from his nose but aimed between his eyes. He could smell the gunpowder. It had recently been fired, he noted bluntly.
   "Aren't you afraid?" Troy asked him.
    Evan's eyes lifted from the gun to look at its wielder. "Not really. I have a feeling you're not really going to shoot-"
    "Shut up Evan! Just shut up!" Troy said, suddenly out of control. The dam that had been holding back his emotions had finally broken apart, rage and pain as clear on his face as night and day, and his eyes burned with an inextinguishable fire.
    Evan closed his mouth. His calm was only a reaction of his shock. Soon the fear would overtake him. He had to stay calm or things could end badly, for him.
    "I want you to kneel Evan," Troy said, "Kneel and beg me for your life! Just like you made my brother beg for his life!"
     "Troy-"
     "Don't deny it Evan! You killed him! I saw you kill him!"
     "Yes, I killed him," Evan said, "I put a gun to his head, pulled the trigger, and blew his brains out the back of his skull."
      "Now watch me do the same to you!" Troy shouted. Without another hesitation, he pulled back the hammer and fired the gun.
      In that split millisecond before the bullet hit him, Evan's final thought was, If only you knew why.
