Betrayal: to the perpetrator
it is a realization of a reprioritization. One discovers (this is the 'heroic' self view) that one values a hierarchy different than one first imagined. One feels the 'betrayal' to be 'being true to oneself' and correcting an error in the balance. To not act in such a manner becomes betrayal of the self.
Betrayal is only in the eyes, then of the betrayed; a belief in another being.
This is the highest form of self buffering... in the eye of the betrayer.
In 'betrayal,' a false idea is destroyed (or rather an idea is shown to be false). What creates a 'betrayal' is when this idea is sacred to an entity. Thus, to remedy betrayal, one of two things must happen. The idea must be reasserted as sacred or the belief in its sanctity must be abandoned.
