Sodom and Givah

There is a comparison made between the evil people of Sodom and the incident of פילגש בגבעה. In the latter case a group of evil people from the Tribe of Benjamin gang raped a concubine in Givah, and ultimately murdered her. As heinous the crime of the Binyaminites was, Sodom was much worse. With Lot, ALL of the residents of Sodom tried to attack his guests. In the Givah case, it was only a small band of criminals. In Sodom, there was a concerted effort to frighten foreigners who entered their city. This was not true in Givah. The people of Sodom came with the intent to commit murder. In the Givah case, they did not intend to kill the concubine. They did not realize how mortally they hurt her. And finally, the Givah case led to a national outcry and protest for this unspeakable crime. There was no such protest in Sodom. This is why Sodom needed to be destroyed, while the people of Binyamin ultimately did Teshuva and were reinstated as part of עם ישראל.
