in a world overrun by the walking dead,and the population of the living dwindling,any reasonable survivor must agree that the likeliness of killing off each and every one of the infected is nearly impossible.this is where my proposition comes in-i have been studying the work of a russian scientist by the name of Ivan Pavlov,perhaps you've heard of him?He is most noted for his work of the nervous system and its response to stimuli.he had trained dogs to respond to certian stimuli,such as a bell.when they heard the bell,they knew food was coming,so their mouths would being to water. i believe the same principal can be applied to the 'undead'. though they are essentially dead,they still respond to basic stimuli as you and i [and even Pavlov's Dogs. . .] would...if we can train them, domesticate them, to ignor that stimuli that causes them to attack,with the purpose to feed, [seeing as they have no real need for sustenence. . .] we can therefore eliminate the threat that they cause,thus making it considerably easier to dispose of them safely.
