Darkness or Light? Philosophy in Knights of the Old Republic.

Let's put it this way, in every universe (and I think everyone understands that I'm not talking about space...), there is good and there is evil. In Star Wars, the Sith, to a greater or lesser extent, embody evil, just as the Jedi embody good.
What makes the Sith better than the Jedi? They live serving themselves, they do what they want, they don't obey an order or a code like the Jedi do.
In general, if there is no evil, then there will be no one to oppose it.

Good and evil are two sides of the same coin, which cannot be fully expressed in any being... Even, in my personal opinion, God and Satan are not absolute representatives of good and evil, respectively...
Therefore, it is more natural to divide the opposition in Star Wars into "Light and Darkness." However, "Light and Darkness" are not complete synonyms for "Good and Evil" - they are diluted and presented as something that has both advantages and disadvantages - it's just that, in general, the advantages of "light" outweigh the disadvantages, which is exactly the opposite for "darkness"...
So, what can be considered purely "good" is what best suits your (individual) point of view... For Drakkosha, it will be the Jedi, serving the code and the "Light," and for me, "good" will be "Darkness," freedom, personal choice, and the Sith's pursuit of personal power :) Everyone has their own point of view
