After Lot's wife died because she longed to return to the filth of Sodom, he lapsed into foolishness again when his daughters got him too drunk to see straight (Gen 19). Contrast this with what Abraham did after Sarah died. He gave strict instructions to Eliezer to find the right kind of wife for Isaac and to avoid the wrong kind of wife at all costs. Both men became the fathers of nations, but the name of one is reviled by nearly everyone, while the name of the other is honored by billions.
