So, you’re going to posit that people with a different lifestyle are evil? That’s pretty fucked up.
They needed Force Using "Antagonists" post 35 ABY after "The Rise of SkyWalker" ended.
With Palpatine Gone, his cult followers defeated/arrested/destroyed.
The First Order is gone.
Where are you going to find "That Many Force Users" to write stories about?
I needed a Mafia Family like setting spread amongst the stars.
With the entire Family being filled with Force Users.
And I needed to mass produce MANY Force Users for my setting.
My new "Rule of 2" would very well over a short period of time to mass produce "Force Users" in secret.
They wanted something to be upset about, I gave them what they wanted.
Even if 99.99999% of the family never do anything "Bad/Evil" by traditional definition other than live a different life style.
Which the vast majority of people won't care about.
But for the tiny amount of Force Users who do something "Bad/Evil", we have a proper setting for it as to how they came to be, and how they managed to have so much power, seemingly out of nowhere.
I just don't want it to be the driving force of a whole group because romantic relationships are my least favorite aspect in Star Wars, with some exceptions.
It's the setup to get "That many Force Users" to exist within the Star Wars Universe moving forward.
