The power of evil isn’t real.
Rather, it’s real only if we let it be real. It wins the hand only if we believe there’s something behind the bluff. But there’s not. It only derives power from our fear of it. To destroy it, we must call the bluff.
Calling the bluff reveals the weakness of evil. That is what it most fears.
Sometimes when you call a bluff you get hurt. You can get taken out by a bluff hand that gets lucky. But even then, the process of revealing the bluff takes power away from the bluffer. Even if you have to be martyred, your act of forcing the bluffer to show their hand reveals them as a bluffer and their power crumbles.
