It is entertaining how egos get bruised when (expected) loyalty gets compromised.
The guy in a management role acts hurt when one of “his” top players acts against his interests, or is just not grateful for the chance of being on the team. The vendor just can’t get it when the client moves on; after all he did for her! Etc.
Individuals have absolutely no ground to expect loyalty from each other. The foundation of true loyalty is always supra-individual: principles or values; from another aspect: superiority, since the foundation of vertical differentiation may only be supra individual faculties.
When loyalty is geared towards individual or sub-individual faculties the style elements are always inferior: impulsive, uncontrolled, dishonest, opportunistic, manipulative, suspicious, fearful, etc.
Past examples of true loyalty include that towards the principles of royalty (intellectual and spiritual dominance, control over power, etc.), the principle of virility (independence, detachment, sense of purpose), the principle of wisdom (differentiation).
Current examples of false loyalty include that towards various forms of money, profit oriented institutions and positions/titles therein, character traits (be it positive or negative), or behavior that is driven by a sense of sin, self deprecation or sentimentalism.
