Tom Kelly argues that eugenics programs aimed at eliminating "zombie genes" would be ineffective and unethical. While some view zombies as a genetic disease, others see it as a contagious condition, with different policy implications. Historically, reactions to outbreaks have varied depending on whether the condition was seen as genetic or contagious, with genetic views sometimes leading to misguided and harmful eugenics policies rather than coexistence and understanding between the affected and unaffected.
