Russian Roulette
Let us say you put one bullet in a pistol, spin the chamber and shoot your wife. There is a 0.16 probability she will be hit. If she is hit, and you go to court, is the fact there was only a 0.16 probability sufficient to excuse you of murder? Of course, not. When you buy a gun there much higher chance it will kill a family member that protect you from an intruder. You know this, but you buy the gun anyway. If you accidentally kill a family member, or if you leave the gun when a child can play with it and shoot themselves, you have effectively committed premeditated murder. What you did is very much like playing Russian roulette with a pistol with a many chambers.
