I don’t think Kreia is a Jedi-basher… She is a Force-basher.
“I hate the force. I hate that it seems to have a will, that it would use us as tools to achieve some semblance of balance.”
And she isn’t wrong. Every conflict in Star Wars has been primarily in the pursuit of balance in the Force, only for it to become unbalanced soon after. Kreia sees both Jedi, Sith and anyone dependent on the Force as weaklings, masquerading as being somehow above those not sensitive in the Force. Finding an arrogance in that because it is Strength given to them by some outside thing, not because they themselves are more capable in anyway.
“The true measure of strength is to turn away from strength that is not your own.”
And there is a profound truth to that.
Edit: In some ways, that is why I think the Kaldorei rejection of the Arcane is totally reasonable, and even the right thing to do. It cultivated the ego. Mage, especially of Azshara’s era, used the Arcane as a status symbol. Being powerful in magic meant that you were better than others. We see this in Gul’dan when he slaughtered his Village with his new power. We see this with illidan, so self important that he thinks he is justified slaughtering his friends for power. We see this with magic addiction of the elves, we see this in Elisand, to a lesser degree we see this in Khadgar, Antonitas, Kalecgos… Despite power not being a deciding factor to serve on the council of six, the most powerful still typically find their way there or at least in some position of authority over others.
Why? What does a study of the Arcane have anything to do with being a capable leader?
Take away the Arcane from a powerful mage and what do you have? Probably a weakling who would be cutdown by trash mobs. Someone so used to conjuring their own food, they have no idea how else to feed themselves. So used to teleportation, the confines and labor of travel is exhausting for them. Honestly, take the Arcane from a mage and you end up with someone rather pathetic… Yet, these adult infants are influencers of global events because they can shoot lightning out of their hands.
