The truth is that laws and religion go hand and hand because we needed to give humans something to fear as well as something to obey. This is the reason why we came up with the Ten Commandments and we also came up with a bunch of laws to keep people from destroying each other in massive numbers. There is no doubt that human beings are flawed and self-destructive and without these rules the world would be in total chaos within days.
That is the main reason why we came up with the laws that are currently being held in different areas of the world. Most of them have the core and the basics in common but we had to adjust them to the many religious backgrounds that are scattered around the globe. The main concern of the order is that religion is starting to lose effect and humans are evolving past this smoke screen. We need to develop something new soon.
