To understand my answer you must understand what the Star Wars Galaxy truly is.
The Star Wars galaxy at its core is a galaxy governed, ruled, and enslaved by an extremely active, omnipresent, and malevolent Fate - both Light and Dark are the intrinsically flawed creations...of Fate itself.
The Force/Destiny/Fate creates a light side and a dark side picks its champions for both sides and pits them against one another with everyone else in the galaxy - all those normal men, women, and children born without Destiny's yoke pressing down on their souls - getting caught in the crossfire.
I will start by shocking you. The Light Side has a very clear, very deep, very persistent hypocrisy to it. Yes, it claims to value personal 'life' and personal 'freedom' but it subordinates both to 'listening to the Will of the force' and fulfilling the purpose of Destiny - an external force that lesser beings are told to trust and worship without question.
Fate is a collectivist argument that promotes servitude to the rule of Destiny's chosen champions - the light side or the Jedi. It creates and channels a dependence on the Jedi to solve their problems giving rise to indolence, corruption, and moral decay...setting the stage for the Dark Side to rise again. Destiny wants only its champions to have intrinsic worth since those are the people it directly controls...everyone else is its meat and drink...its bloody spectacle...its entertainment...
In other words, the Jedi are the ones Fate acts through directly and it uses them to reinforce its grip on the rest of humanity. No Jedi ever earns their high place in the galaxy. Destiny makes its picks, fills those champions up with free power, and charts their actions from cradle to grave making their arrogance, pride, angst, and whining all the more infuriating, childish, and insultingly stupid to those born outside the loins of the chosen few royalist families Destiny loves to play with...
Bottom Line, thee Jedi do not earn their power through merit or personal achievement but from 'royal birth' into the right families or the puckish whims of a galaxy spanning Fate that plays mortals like puppets for the sake of its own amusement. Think of Light Side as Destiny's favored side in a very bloody game of football and the Dark side as everybody that may oppose Fate's control over them. Fearing the Dark Side, Fate stacks the deck by supplying the dark side with force-sensitives who are twisted into corrupt mockeries of themselves that don't hesitate to grind them up with the end result of all Sith philosophies.
All Force-sensitives are enslaved by Destiny's yoke on their soul from birth and gain Fate's incredible superhero powers to act in its interests. Dark side force-sensitives are Fate's way of culling all those who value personal liberty and personal merit and personal value from the galactic population pool of souls while simultaneously discrediting an individualistic value system and worldview that threatens its stranglehold over creation and its very existence.
So yes, Fate uses the light side as a proxy for its own side (and point of view). Destiny twists the other side the Dark Side into a hateful mockery of its own ideals so that a Destiny centric position is "proven" correct as a result of whatever its most recent force-sensitive controlled war of annihilation and conversion happened to be.
Its viewpoints are reinforced among normal human beings (who as a rule don't want to die) along with every other non-force wielding sentient while culling the herd of the rest.
The truest ideal of the Dark Side is to overcome Fate in the hopes of creating a utopia where Fate falls to the personal liberty of the individual who earns his or her successes in life instead of having those successes handed to him or her by Fate...Fate deliberately warped this ideal by twisting some of the children whose yoke of Destiny is stronger than any other into malevolent mockeries of this ideal. This is shown by those force sensitives who are the worst sort of death seeking blood knighted power hungry tyrants who routinely try to crush the liberty and personal value of those 'beneath them' until it utterly takes their lives allowing Destiny to collect their souls and torture them.
Thus the deepest truth in Star Wars is that most of humanity and every other sentient is mere grist for the mill of the bloody whetstone of Destiny...any personal accomplishment or determination is rendered meaningless by those Fated to succeed over them...and an individualistic point of view is discredited by the Destiny's dark-sided children.
In summary, all wars in Star Wars are tools of Fate to preserve itself from all those who have Free Will. The Light side and Dark side are false artificial sides controlled by Destiny so that Fate may reinforce its Will and trample on the will of the vast multitudes who exist outside its direct control using a relative handful of people that it can control directly to serve its interests as well as provide it with its chosen form of entertainment.
