For a child, perhaps. It is a banal, shallow and upon more serious inspection incoherent arbiter, and most certainly not moral one.
Is it? Or could Kreia be wrong on all counts? If the Force ceased to be an influencing factor how do you know things would get better and not worse? No Jedi, no Sith. All actors unrestrained by any morals. Number of wars might go up, length of them could increase and frequency of occurrence could go through the roof. No way of knowing for certain.
You conflate morality with the Force. But within the (Star Wars) universe you still have countless civilisations where the Force plays minor role, or none at all. It is the work of the Force, Jedi and the Sith to have constructed a religion and moral foundation out of the Force, as if objective morality is in any way dependent on there being a supernatural magic-like people roaming around. It is not. In fact, originally the Force was something mythical, and force users were considered extinct, extremely rare or a combination of myth and reality. The Force is not moral and is not needed for morality.
Perhaps the scope, viciousness and length of wars would decrease. It is the Force which has fueled the biggest atrocities, with or without using the technology. It is the
unnatural abilities of the Sith which enabled them to wipe out whole planets with ease.
This is what she claims to value in its removal but I think that's only the surface of it. The reality of it is this: There are very few Jedi who ever fall and even fewer galaxy spanning wars. Over the course of ~25,000 years you can count them on two or three hands.
Perhaps, but a single Sith is capable of undoing the supposed millennia of peace, progress, wealth and good. To be honest, this sort of points out to Jedi being so pathetic, which they are. But quantity here matters little when in the grand scheme of things, through the workings of the Force, it all has to be balanced. Suffering is more extreme than its absence, when it comes to how it's experienced, so it takes just s few decades to cause such misery that rivals or surpasses these millennia of peace.
It is impossible to agree with her and think the way you do.
I think what Kreia is reeling against is that some beings in the galaxy are selected for a higher purpose and have no choice in the matter, overriding their soaring desires and crippling their ability to overcome their own struggles through merit. This is the basis on which I agree with her. She is correct in this regard for certain and therefore the Force should be removed.
Her greatest contribution is in pointing out how the Force seeks to balance things. Jedi, in their blind belief in the duality of the Force, thought that this balance is precisely only the good things, or what we could say are good things (there are good things which cannot be expressed without there being evil in the first place, and all good things must come to pass). But they are mistaken, and the Force in its own will has a different position, one where the "dark side" also has to express itself. And in equal measure.
So in the end it ends up like a zero-sum game. Which, actually, is bad. For if the sum of all is one big nothing, then it is bad, for nothingness isn't of value or goodness, but is instead something to be avoided. The entire effort and time of Jedi and Sith everywhere, at a galactic scale, is one big nothing.
