Rabbi Moshe ben Nachman, the towering medieval scholar, writes with refreshing clarity:
“The sword is not the cause of murder, and there is no sin upon him who made it.”
In other words, a weapon, be it a sword or a gun, is neutral. It can be used for good or evil. Thus to label a gun as “bad” makes no sense, for a gun can be used in self-defense which the Torah sees as an obligation.
