Everyone in this story is sinful: concubine, Levite, the old man, and the men of Gibeah. In the moral chaos of Israel the Levite man resorts to gruesome theatrics in order to generate enough moral outrage to obtain justice.This is what happens when everyone does what they want, with no moral compass or "true north" Anarchy. A competition in outrage theater. This was Israel at the end of the period of Judges. This is our current society. We should not be surprised when sinners are sinners… but the people of God should be different. We should be salt and light, changing the moral and spiritual atmosphere through our presence and our example.
