It would depend on what level of death, undeath, or life that the dead were raised to.
(1) The way it’s really done in Haiti and in a couple of places here in Memphis, where a tetrodotoxin from the puffer fish (mixed with common, ordinary dirt—the mixture is called ;goofer dust’) paralyses the victim who appears dead and is buried. Brain damage occurs due to lack of oxygen. The victim is dug up and is in a stupor and brain damaged but suseptable to suggestion and becomes a mentally deficient slave. That’s how we do zombies in Memphis,
(2) The dead are really dead and putrid and maggoty but reanimated to life—not really “alive” but reanimated corpses. They aren’t good for much but crashing and stinking up teen parties, Or reintroducing some girl to her boyfriend now a walking corpse. I assume they still think stupor-like thoughts and miss their former lives and try to reconnect with their loved ones and work associates.
(3) Where they are similar to #2 but alive again, just in an advanced state of decay;
(4) Those whose death is “cured” completely and they are alive again and can go about their former lives for a few more years at least.
You usually have to make a deal with the devil for such smooth results, but there are usually unexpected consequences for the living, or some consequences for the reanimated that involves eternity, hell, etc when death comes ‘round again,
