Sometimes the OP's philosophical/spiritual question almost answers itself when you deal with someone that you only think you know. At an indoor range I ran into a kid that I know from local events. He does, or was doing, at least, certain marketing chores as an IC for Geissele, so I figured, incorrectly, that he was a little more aware of various firearms MOA and range etiquette than he actually turned out to be. Long story short, he asked to try one of my S&W revolvers. Rather than load it for him and cover ground rules, I put it on the table cylinder-out and muzzle-forward and let him load it. Mistake. He loads it, spins the cylinder like he thinks he's Bat-effin'-Masterson, and then tries to Dick Tracy wrist-snap the cylinder back into place. Before he managed to lay a finger out perpendicular to and over the forcing cone, I stopped him cold. People need training, and it's a mistake to think that ownership is enough to make the average overconfident enthusiast safe.
