You might prefer ‘judicious’ or ‘justifiable.’ That is your prerogative. I sit awake and torture myself wondering whether I’ve done all I can and that is mine.
The gun is not justice, in and of itself, just as it is not evil or murder. The gun is a thing just as you are a person and the steel cannot bless your actions just as it cannot be cursed by those lawmakers who would ascrine intention to the inanimate.
The gun is a tool, in your hand as in mine, and it brings no righteousness to the works of those hands.
The use of lethal force is just in such cases as it prevents death or grievous bodily harm. It is wrong and generally illegal to use lethal force in the defense of property or pride. You may use the gun to harm only when you prevent greater harm from being done.
It is not right to shoot to kill. Having shot to stop a threat, it is not right to shoot to prevent badguy’s pending lawsuit. If badguy is incapacitated or immobilized, you must let him live, and call upon the services of modern medicine to save his life.
I understand the desire to kill the evildoer who has wronged you. I conprehend the call to kill the killer who can bring pain to your family, to prevent the theft of your property and things or to stop the sinister intent of the interloper. But my understanding is not force of law.
Please, if you carry a gun, learn to use it. Please, in your learning to use, learn also to have appropriate mercy upon those you might otherwise end. I beg you for the sake of the evildoer as well as the eternal right to keep arms and bear them in our own defense.
