It's always funny how it goes like "The monsters killed my parents, destroyed our village, etc. They can't ever be forgiven and must be eliminated" while at the same time the adventurers wander into the dungeon every day to slay countless monsters to harvest resources. But I suppose that's how it goes. In order to continue the life of adventurers and the economy of the whole city, average people must absolutely stick to that notion. There could always be outliers, who would have their own struggles but continue nonetheless (if they can continue), but as Finn noted, that won't work for the masses.
