Do not be envious of evil men, Nor desire to be with them; Prov 24:1
Lot’s choice of Sodom and Gomorrah was not a good one.
I think the wickedness of the cities was well known and perhaps Lot thought he could keep his distance or not be affected.
But do not be deceived:”Evil company corrupts good habits.” 1 Cor 15:33
Since Lot was a wealthy man with large herds, what better place to do business that a city.
The people needed goods and he was the closest supplier.
Perhaps he found trading in the city easy.
And, as it is today, was readily accepted by the men of Sodom and he would be.
They only seek to make others like themselves.
If sinners entice you, do not consent. If they say, “Come with us, let us lie in wait to shed blood; let us lurk secretly for the innocent without cause; Let us swallow them alive like Sheol, and whole, like those who go down to the Pit; we shall find all kinds of precious possessions, we shall fill our houses with spoil; cast in your lot among us, let us all have one purse” — My son, do not walk in the way with them, keep your foot from their path; For their feet run to evil, and they make haste to shed blood. Prov 1:10-16
