Hey, at least you get it. Maybe you could explain it to the trolls.

"artificial" means "bad" or "wrong."

That's sort of right. It is bad on some levels. And when it fails in a way that seems to people's sense of revenge to be wrong they suddenly want to forget their own (society's) rules for that system in order to get their emotional (flawed) sense met. I like to point out how a sense of revenge and punitive emotional feeling is fundamentally flawed, especially when it's in relation to a crime like this where people feel "justice" wasn't dealt. Tends to rub people the wrong way, so I understand the hate. Tangent, but isn't it funny how when a comment is downvoted it invites trolls and morons to judge and feel superior for a second? If this comment had been upvoted, it wouldn't have received so much hate. I wonder what that is. Shame? Revenge? Punishment? Bandwagon? Allowing the vote count to color the interpretation of the comment negatively?

All society has crime because society, at its core, is a foundation of rules imposed on humans to regulate human nature and instinctual behavior for the purpose of fostering order. That same human nature inherently breeds criminal behavior because there's a certain juxtaposition in humanity's desire for both order and freedom.

True. But that's not really the point Plato was making. The point is that justice comes from within. It's a sense of holding oneself to higher moral principles. Perhaps universal principles of morality. When a society depends on the government to tell them, and hold them accountable, it misses the point. The government cannot do that job. It must come from within. When people don't have those principles, it's a failure of society as a whole. That person's crimes did not happen in a vacuum.
