Think about how many horror movies have been made featuring grisly death ,and how those movies are wildy popular. Think about the murder mystery books which are likewise popular. The mobster fiction with incessant depiction of crazed killers.
Or how about the babies dismembered in the womb by the millions ?
The "civilized" world is awash in cold- and hot-blooded murderers !
Perhaps Lot has spoken with God and he has found there are still enough good people to stay His Vengeance as wreaked on Sodom and Gomorrah.
