The author only cares about boobs and asses. Nothing else matters. Such as the stupid economy of whoever kills bandits can keep everything they had stolen, robbed, and hoarded. Who would become a bandit when you could just become a corrupt adventurer? First kill the merchants yourself, but report to the authorities that the merchants were killed by bandits, whom you then killed in turn. Just say you burned the bandit corpses somewhere out there, to avoid the corpses attracting monsters or turning undead if that's a thing in this story. Now all the stuff the merchants were carrying is yours perfectly legally, even if the merchants' associates/family recognised all of the items.
That really boosts the economy and encourages people to become merchants, haha. But like a saying goes in my corner of the world: if you have been given a spoonful, nobody can demand a ladleful from you. This is the author's limit.
