The Sodomites hadn't shown any interest in abusing Lot's family before God came to judge them. When Lot offered to send his daughters out to them instead of his two guests, he shouldn't have been surprised when they declined. The object of their lust and wrath appeared to be directed at strangers rather than their own people. They were guilty of terrible sexual sins and idolatry, but the defining characteristic of their wickedness seems to have been hostility to strangers.
