Cliches often capture a truthfulness none of us really comprehend; easy to say but rarely put into perspective. "It's not the gun that kills; it's the one who uses it" has been spoken more often than could ever be counted; unfortunately, often after the fact, when a gun has been used as a weapon to take innocent life, be it murder or suicide.
As a citizen of a country where we have a right to bear arms, I own a handgun. I, as a moral person, would not use it to harm another unless it was to defend myself, my family or my home. I know it is morally wrong to use my gun as a means of causing harm to those who cause no threat to me. I obtained my gun lawfully. To obey the laws of the land is a moral obligation.
There is validity in the cliche "It's not the gun that kills; it's the one who uses it." Until such time as morality becomes the driving force behind our society, guns will continue to be used to take innocent life, as will knives, fists, narcotics and any other means an immoral person can conceive and orchestrate.
And a moral person does not get behind the wheel of a car when incapacitated, knowing that he or she might be responsible for taking his or her own life or the life of another. This brings to mind another cliche: "It's not the car that kills; it's the driver" -- another moral choice.
