If you seek for supreme predator, go find God. He hunts the prime killer of mankind, the Satan.
Every time we exterminate a predator, we are in a sense creating a new predator.
Fear is the venom impact of predator sting, causing prey not to be focus on the survival.

I might be manipulating you to create risk for myself.
