Zombies, corpses said to be brought back to life in full decay with maggots intact, to lurch around threatening the living, whilst bereft of consciousness and character, bereft of moral judgment, and under the control of the bokor, that is, those whose dastardly wishes the zombies carry out without care or regard for those they affect deleteriously.
It is one thing to have a ‘local’ zombie who only feasts on his own decayed parts, while attempting to decimate others of a smallish political district.
It is quite another to have zombies who not only feast on the decay within themselves to stay alive– til they cannot stay propped up even by others anymore, even the bokors, but in the meanwhile lurch to destroy others across the world, who did NOT elect that the zombies live in all their superations and gross appetites of greed and vanity, innocents who in fact, never invited the zombies in to their homes, their personal and business lives.
Oddly or ideally, in books and films, often the way to put an end to zombies, is to identify and bump off the bukors, the ones who control and reanimate the decayed puppets.
Object lesson in metaphor.
