Feelings of any kind are not known to the walking dead. Every form of psychological warfare, from attempts at enraging the undead to provoking pity have all met with disaster. Joy, sadness, confidence, anxiety, love, hatred, fear—all of these feelings and thousands more that make up the human “heart” are as useless to the living dead as the organ of the same name. Who knows if this is humanity’s greatest weakness or strength? The debate continues, and probably will forever.
