But now imagine that half the town has good reason to fear this monster — credible reports from people they trust, centuries of documentation from other towns — while the other half has equally good reason to believe that these reports are fables. One side believes, in good faith, that these strict rules are all that protect the town from a horrible fate; the other, that these rules harm, punish, exile, or even kill them for no legitimate reason at all, other than the power of the first side. So long as there is real uncertainty about the monster, each side has good reason to view the other as an existential threat.
