**For others God knocks them over the head and yanks them out of Sodom**
They weren’t supposed to be there in the first place. They had dwelt with God’s annointed and chose (free will) to go to Sodom. Lot’s wife’s free will turned her into a pillar of salt.
I would suggest it wasn't Lot's "free will" that caused him to go to Sodom. Please review your scripture:
This is the way sin works. We aren't "free" to make choices. We follow our desires or we trust in God. We either indulge in the things of this world or we reject it. As for Lot's wife, she looked back. And as our Lord tells us, those who look back are not fit for the kingdom.
