My avatar speaks words of "darkness where there is no light". We see a lot in people's eyes. We watch how they react to others. Next we find the deceitful ones. We wonder if they are hiding or protecting something. Some don't know which way to turn.
"We could help you better if we just knew what it was you wanted." Might cause a little caution, but is that deceit?
I have found it to be true most people are brought up told to be quiet about things: to look the other way. In the end, it is what most people do when faced with the really bad, but are they really bad?
"I am dedicated to the belief that it is God's will that all men should strive for wisdom in themselves, not look to it from some other. Babes, perhaps, must have their food chewed for them by a nurse, but men may drink and eat of wisdom for themselves.” ― Marion Zimmer Bradley
It takes a wise man to truly distinguish in his own heart what is evil, and what is good." Marion Zimmer Bradley
From King Arthur: Legend of the Sword; " Arthur learns that we all want to look away from the bad. That's what makes the difference between a man and a king; a king looks into the darkness and finds answers." From a review
Personally, most people do not think they can stand up to true darkness, and feel they will be accused of betrayal should they say anything. The presence of a King seems to always bother the darkness, for the darkness knows what a King will do, even in the quiet of his mind: for he is never alone. He will only do what is necessary. Such are we in our walks through life. Always see both sides of the coin.
