"And if you develop a cancer elsewhere in your body, what good have you done for yourself? Do you also avoid driving because you might be in a car accident? "

You're facing a crazed proven killer invading your house. You've got an effective weapon, trained on his center of mass. He starts to turn towards you, and begins to raise his pistol towards you. Your finger tightens on your trigger...

Do you throw your weapon away, saying, "Oh, well; somebody else would probably shoot me some other time, anyway?"
