What are some aspects about the code of hammurabi that show it was an example of a developed legal code that reflected existing hierarchies and facilitated the rule of governments over people?

The existing hierarchies were based around social status and class division. The upper classes would often be punished less severely for their transgressions. For example, if a doctor makes a mistake and kills a poor peasant, then the doctor gets fined. If the doctor makes a mistake and kills a wealthy noble, then he would be punished by death or have his hands cut off or similar things.
