Their shepherds had failed them. Their kings had been a royal nightmare - ruling arbitrarily, placing their own interests above their people's, failing to protect them from foreign invasion, getting them mixed up in international intrigue. They also failed to provide any spiritual leadership, and worshipped whatever gods gave them the political advantage at the moment. Mainly they worshipped their own power. And Jeremiah told them they would have to answer to God for that.
Nobody gladly obeys.
Everybody is his or her own god. Everybody follows his or her own rules, which means there are no rules. There are no absolutes, only opinions, and the common guide most people follow is what they think they can get away with. The moral, civil, and social order is dissolving into chaos because so few people seem bound to much of anything beyond themselves. Thus proving my point.
