The Sith Species (aka Sith Purebloods, Tsis, whatever tf else they call em) being majority all Force sensitive I think influences how they view the Force in comparison to the Jedi a lot. ima break this down by giving two different life experiences
You a Jedi. You was born in the Republic so when you had a midichlorian count of 9.4k, your parents gave you up. Your entire life is the Jedi Order, and its controlled environment. There's always some older Jedi around to guide you, watch you, and tell you to be mindful. Your entire life is engineered to keep you on the Lightside path. You're never truly alone, and while that does give you community. It means that everything is monitored, curated, and kept on the straight narrow. However, it also means that you cant really experience the Force and come to your own conclusions about it because older jedi are always there to guide you. You use the Force in very controlled and educational environments. It's viewed as a great responsibility. One that you always have to make sure you're not mistreating.
Now, ima contrast this with how shit probably be going down for Sith
You're born on Dromund Kaas. You're a Sith Pureblood, so you're force sensitive and when you reach adulthood, you'll have to join the Order like everyone else. Because of the war mostly. However, everybody else in your family/House's Compound also can use the Force. So, for now, it's you, the younger relatives/siblings in your House, some of the older kids, your grandparents, and retired family members. Your grandma is like "Oh, Marka Jr, let me teach you Force Electricity so you can kill Sleen in the basement thats eating all our eggs. im tryna make this birthday cake for your baby brother's one year old birthday" so she teaches you. You go down, and kill the Sleen. And shes like "Yay, Marka Jr, youre gonna be a great Sith Lord one day. Go play with your cousins and let me watch our version of The Price is Right" and then she lets you go outside and you now can flex to all your cousins that grandma taught you some cool shit and you killed a big lizard. Naturally, you gotta show your cousins your new skill. So you force electrocute tf out an fire ant hill that be whooping yall ass everyday. And so now, you're just the cousin that everybody goes to for when some scary ass animal makes it way into your yard. Yeah, maybe you shock somebody when theyre acting up or not listening to you for a second. Then youre older cousins start feeling like you think youre untouchable so they force shock you a lil just to remind you who really runs shit. Whole time, your grandparents and retired aunts and uncles just letting yall kids sort out your own deputes as long as nobody dies.
And I think that that overall causalness towards the Force is why the Sith Purebloods have the culture they do. Them having a very multi-generational family structure means that when they teach their kids some Force ability, it's like teaching them how to mow the lawn or something. Its not like the Jedi where theres all this policing and over guidance. like we'll show you how to do it, but then you gotta complete the task yourself.
It's like when you were growing up and your family would teach you how to do the task, or tell you to do something, and then they'd leave you to do it.
imo this is probably also why Sith training is how it is. It's not bc the Sith Masters are intentionally cruel/removed, it's just the Force is commonplace so ofc they gon show once or twice and expect you to do it.
When you doing the dishes or landry, nobody was standing over your shoulder telling you to "be mindful of your emotions" as you do it. They show you and then youre expected to get it done bc it aint that serious.
