Of course people need moral and ethical training. But the elements of empathy, compassion and recognition of fairness are built in -- or not as the case may be.
an unassembled collection of slide, frame, barrel, barrel bushing, takedown lever, hammer, sear, sear disconnect, trefoil spring, hammerspring, recoil spring, barrel-link, trigger, triggerbar, gip safety, etc... does not equate to a functional pistol. they are the *potential* for one.
as I stated, from the get go: most (or all) are born with the *potential* to have a system of right and wrong. Unless assembled (and, yes, disciplined with pain and humiliation and fear when needed) the human will NEVER get to right and wrong but will remain what he was when born: utterly self-centered.
