I have come to believe over time that if you want to fully test the decency of humans, you should watch how they handle divorce.
The world of divorce is an example of the idea that if you think that you have heard the ultimate story of bad behavior, just wait until the next divorce case that involves a lot of money.
This tale of the divorce of Blatherwick vs. Blatherwick truly has it all. If you wrote this all down as a story, it would probably be rejected for a TV drama series for being too outlandish.
