As for “honor,” a man who might have to switch sides, or join another group, would have to present trustworthiness, so far as not reneging on deals, getting one’s back, and so on. Particularly or especially if he/she is in a violent trade and situations.

Honor is “adaptive” in that it lets humans cooperate in highly risky situations, the higher the personal risk of dying, the more honor is found, examples soldiers under combat conditions.

The reptilian behavior is indicative that Jackson’s entourage found little immediate personal threats to life and limb. Therefore, little loyalty. A low-risk or perceived low-risk society tends to have these sorts of behavioral markers. Things that are “expensive” in terms of behaviors, such as honor, which means forgone exploitative opportunities, are abandoned because the payoff (ability to switch groups to survive) is perceived to be not needed.

Even in a tribal situation, such as say Saddam-era Tikrit, such behavior would not fly, because any who would act like that would not be trusted even by kinsmen, and would therefore be sidelined from risky but high payoff activities that required high levels of trust.

In other words, a short term loot and scoot mentality was the behavior of the Jackson entourage.
