It's spiritually rather like a five year old (A) pointing the finger of blame at their sibling (B) or playmate (C) or even a random kid they heard about (D). A needs to water down or divert attention from their own guilty conscience. A shouldn't be punished because their good, they endure strictures and rules that make them suffer.

They see B, C, or D over there being some way or other that A doesn't like or hasn't the courage for. A knows they are a good child because A can point to how bad B, C. & D are being by not enduring the strictures and rules A must endure. A doesn't feel a lot of kindness and forgiveness, and imagines themselves to be suffering.

In childish pettiness, A demands that B, C, & D must be punished unendingly and cannot be forgiven because A is good but still has all these strictures and rules they believe they must endure. A cannot imagine an existence not weighted under the strictures and rules they believe everyone must endure.
