The Bible is not clear. My hunch is that he knew beforehand. He knew God said that he wouldn't destroy Sodom if he found ten righteous souls there, but if you look at the pattern of questioning, I think he realized that there was practically no one there righteous, and so quit asking at ten.
People seem to overlook the other sexual sins committed by those in Sodom and Gomorrah....
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
