Do you know the story of Lot's wife? If not, you must brush up your Bible-reading. I am kidding of course. Everyone is free to do and think what they want.
(Awkward minute of silence.)
Anyway, what the story tells, is that during the destruction of Sodom and Gomorra, G'd tells Abraham that Lot's family can escape with the condition that they never look back at what they're leaving behind. Everyone obeys this order except Lot's wife, who can't resist the temptation to see what was her home being destroyed.
This has many interpretations which I won't dwelve in because I would be losing all track of my story.
