Armed robbers visit your home. Gives you the gun and tells you to shoot your wife else they would kill you. Because of the love you have for her, you tearfully tell them you can't.
The gun is taken from you and given to your wife. Who collects it...faces you...and pulls the trigger. Fortunately for you...there is no bullet in the gun.
The robbers then smile...collects the gun...and leave.
What would you do?
