Victim gets revenge

My father pressed the steely cold butt of the gun in my hand and whispered his request with pain in his eyes, "Kill me...", I couldn't do it.
"If you don't kill him, I'll kill you both!" an angry voice shouted behind me. The man had kidnapped them. They were in a dark shady room. It was cold and in the distance you could hear the sound of dripping water.
"Shoot him NOW!!"

"NO!" I screamed back at him. I yanked the gun out of my dads hand, pressed it to the other man's forehead, and BAM the bullet came out and entered right where his temple was. The kidnapper was dead.
