Some people need a little sith influence I would have never broken the chains of manic depression and found enlightenment if it wasn't for the sith but it's dangerous like kimo therapy but to the right person in the right setting it can sometimes save your life but only sometimes

One who has freed themselves from all restrictions has reached perfection… their potential fulfilled. Perfect strength, perfect power, perfect destiny."―Yuthura that can be viewed in zen mode or sith mode

The poison of the Dark Force shall manifest in different stages: rage then exhilaration, anger then control, terror then superiority, bewilderment then passion, frustration then victory, despair then power — need we say more?

It says the dark poison can lead to control that's eventually what happened to me

“Why fear to reanimate ALL the possibilities that lie dormant in our natures? Is it not desirable to cultivate all plants indiscriminately? There are those that are poisonous, true, yet even these are indispensable in the practice of medicine. Large doses of certain drugs cause death; but, administered wisely with the hand of a skilful physician, they bring relief and very often a complete cure. The same may be said of many forces that are evil only because they are not disciplined.”
–Yoritomo-Tashi

feeding on rage like this brings fighters to the dark side, but when they step away they can be much more receptive to the light. Not all such warriors are beyond redemption.-luke skywalker

Yes they can be more receptive to the light when they turn away from the dark side if you look really close not all sith philosophy is evil some of it is necessary to advance for certain individuals it accelerateted my decent into enlightenment I was once a victim and it made me strong. I learned how to first replace all negative emotions with hate then I learned how to let go of the hate and nothing else was there

Morality is not a simple set of rules. It's a very complex struggle of conflicting patterns of values. This conflict is the residue of evolution. As new patters evolve they come into conflict with old ones. Each stage of evolution creates in its wake a wash of problems.
Pirsig, Robert M.

Sometimes the insane and the contrarians and the ones who are closest to suicide are the most valuable people society has. They may be precursors of social change. They’ve taken the burdens of the culture onto themselves, and in their struggle to solve their own problems they’re solving problems for the culture as well.
Robert M. Pirsig

The Sith and the Jedi are similar in almost every way. Including their quest for greater power. -Darth Sidious

"I don't know, I guess I've come to a point where anything that's not intellectually stimulating in some way other than a way that challenges the people to either be creative or have to think about something in it's entirety is moronic and as such is worthless."
- Darth Atrer

“Wealth and material goods mean nothing to me. I crave only power and purpose. With power, anything you want or need can simply be taken. With purpose, your life has meaning.” ~ Darth Cognus

“Light will for a time have to be called darkness: this is the path you must tread.”
–Friedrich Nietzsche, Human, All Too Human

“The dark side will devour those who lack the power to control it. It’s a fierce storm of emotion that annihilates anything in its path. It lays waste to the weak and unworthy. But those who are strong can ride the storm winds to unfathomable heights. They can unlock their true potential; they can sever the chains that bind them; they can dominate the world around them. Only those with the power to control the dark side can ever truly be free.”
~Darth Bane

Once you have learned to control it you don't need it much anymore if your me


“It is the internal struggles, when fought and won on their own, that yield the strongest rewards.” ~Darth Traya

“You’re afraid that my words might be true. That the dark side doesn’t corrupt in and of itself. That you’re destined to become the next Sith Lord… Because if it is true, you have to make a decision, choosing between your life as it is—comfortable, but almost purposeless—and life as you know it should be.” ~Lumiya

“To understand the dark side you must suffer through hardship and struggle.”
~Darth Bane

Now the one I've been looking for

“The weak will always be victims. That is the way of the universe. The strong take what they want, and the weak suffer at their hands. That is their fate; it is inevitable. Only the strong survive, because only the strong deserve to.
I know what it means to suffer. I used to be a victim. But I refused to accept my lot in life. I made myself strong. Those who are victims have no one to blame but themselves. They do not deserve pity; they are victims because of their own failures and weaknesses.”
~Darth Bane

Before the sith I lacked the strength to be enlightened I was once like how darth bane founder of the sith was but I learned to be strong. I corrected myself, I got rid of my manic depression through my own rendering of dark teachings
the dark side freed the bonds that held me down and freed my mind like it promises. When I was done with it I moved on to bigger and better things and if my strength ever starts to falter I can call apon it again till I move on again it keeps me balanced. To achieve perfect balance you might wanna consider learning to control both sides of the Force the cancel each other out
