Genesis 19:32 - Joseph Benson’s Commentary on the Old and New Testaments

Come, let us make our father drink wine Although, upon the whole, Lot was a righteous man, and possessed of many amiable qualities, yet it evidently appears that his principles also, as well as those of his daughters, had suffered some degree of contamination by the society of evil-doers, otherwise surely he would have withstood every temptation to excess of drinking. Here the history of Lot ends; after this we hear no more of him or of his daughters. We cannot but be sorry to leave them under so dark a cloud. He, indeed, we have reason to believe, lived to repent of his sin, otherwise St. Peter would not have spoken so honourably of him; but we have no proof that his daughters repented of theirs. And certainly the children thus desired, and in this unlawful way obtained, were monuments of their own and their father's reproach, and the names they thought fit to give them, which descended to their posterity, perpetuated the memory of their sin and shame to all generations: Moab signifying, of my father, and Ben-Ammi, the son of my people.
