Any firearm is only an instrument.
It contains no evil, no conscience, and no ability. It is strictly the intent, competence, and character of its user that decide the outcome of any and all actions taken with it. The right to self defense is one of the inalienable God-given rights, while the Second Amendment is a right granted by the Constitution to preserve freedom. Both are individual rights as well as responsibilities which can never be delegated. If the firearm is chosen for defense, it should never be the sole source of any defensive strategy.
