To hurt another with ill intention, is simply to hurt oneself. This is because the subject is denying that we are a human family. Even if we appear to be separated by bodies, we are connected in a way beyond the physical.
Your statement seems to imply (correct me if I'm wrong) that God is angry, and vengeful; finding it necessary to punish his children for their misdeeds. Yet I am proposing that we are simply victimizing ourselves by treating others poorly. Is not living with this self inflicted Guilt hellish enough? Must I really worry of double punishment?
