Star Wars movie right and wrong

How do people determine what is right and wrong, and who determines right and wrong for the masses?

Answering the question above while analyzing the history and values between the Old Republic/Galactic Republic and the Galactic Empire/First Order in the Star Wars films

Below are the instructions given from my professor.  The artifact referred to below will be the Star Wars Republics

Prompt
For this project, you will critically  analyze an artifact (see choosing your artifact below for more on what I mean by artifact). The artifact you choose should help you better understand a question or problem you want to examine. In your essay, you should give a detailed description of the artifact and help your readers see why this artifact requires analysis, or why they should care. Present to readers your understanding of the artifact, using evidence and examples so that readers understand your claims. Be sure to acknowledge and consider alternative perspectives would everyone have the same relationship to this artifact that you do? Consider carefully the intended readers and help them see why the artifact is relevant or affects their lives. 

Analyzing your artifact: This is the first assignment in this class that requires analysis, so lets state what that means. When you analyze something, you break down the various details of an artifact and show how you understand those details. The details you analyze can include text, but also might be visual, audio, tactile or other kinds of details.  As you connect details to meaning in this way, look for patterns. Do the meanings of various details consistently point to one main idea, or are there multiple ideas that clash in your artifact? And how do the patterns of meaning you find give you insight into the question you started with?
