Here is the complete text of Law 15 from the 48 Laws of Power by Robert Greene. This law is pretty disturbing to most people as it pretty much goes against the teachings of the New Testament. Jesus, as you might recall, advises you to “turn the other cheek” and “let by-gones be by-gones”. Instead, this law requires that you identify who is an enemy and who is not. Those that are identified as an enemy must be slain completely and totally.
