I told Ustad about my experience and the thoughts around it. Based on physical similarities of a character, I looked at the guy with a subjective-perspective.
"That's so common!" was the reply of Ustad. "You don't need to be literate to understand the pictures and visual expressions. It's our innate ability to connect the visual expressions with our environments..."
"So, you think that my brain has borrowed the character of Kemper from the show as a visual representation of the term, "serial killer"?" I interrupted Ustad.
"That's my best guess!" he answered. "Look! it's a common phenomenon if you pay attention. For example, the combination of beard, Afghani dress, and turban have become a visual representation of terror and the combination of clean-shaved face and western dress have become the expression of liberalism?"
"I kind of agree!"
"What I have been interested are the ways most of the people use these symbolic representations!" Ustad continued.
"I didn't get you!"
