Beat the game (LS), figured might as well share a few opinions.
It's Rambling Time!
In many ways, I cannot but sympathsize with the Last Boss's cause. After all, this game is more or less a criticism of George Luca's rather shallow Mythology. The more I think about it, the more I would have convinced myself to destroy the Force if given the chance/option.
First of all, Kriea's education has always been about tough love. You don't help the beggar, not because you are a jackass, but because it will not make him an self-sufficient person by doing so. In another word, you are helping him (despite the beggar's objections). Sometimes, the instinct to help others will only harm them in the end -- such is in the case of the Mandalorian Wars. How could one (The Republic, in this case) be self-sufficent and strong if he always relies on someone or something else? In many ways, Kriea's philosophy reminds of Rousseau's adulation for the strength and perfectibility of Natural Man (civilized man, when stripped of his artificial strengths, is by far weaker than natural man). Likewise, the Force is a crutch for the people. Obviously, some Star Wars civilization have managed to flourish (strengthwise and morally) without having to rely on the force. And let us look at the Rakata on the other hand, their reliance on the force have lead their civilizaiton into utter destruction.
Lucas has created the Force as a self-contradicting being (Good must coexist with Evil). I understand that this view a popular cultural thing, but it is a ridiculous idea* . I am pretty certain that the Ying-Yang philosophy (which is obviously the reference) does not make the analogy of Good and Evil. WHY should Good and Evil balance out in the end? WHY shouldn't Good triumph over Evil? A moral person, in the end, will find the Force to be an atrocity. The Force is a tyrant (for it have control over Fate) which imposes its amoral balance upon mortals.
I could ramble even further, but I'll just outline the main arguments.
Why one should destroy the Force:
For one's own advantage, or good:
1) Becuase reliance of the Force will only lead to weakness (like the Rakata)
For one's own love for freedom:
2) The Force is a tyrant, it leaves mortals no room for free will.
For one's own moral world:
3) The Force's philosophy is amoral. With its power over fate, the struggle between good and evil is but a perpetual cycle. Neither side is more "justified" than the other. I, for one, would not like to live in a world where Evil deserves an equal merit of existence as Good would.
So, in under this light, I can not but find Kriea's cause to be (even morally?) justified. Of course, we have to presuppose that destroying the force will not have some ridiculously harmful reprecussions such as killing everything in the universe....
*It seems to me that the main philosophical argument for why Good cannto exist without Evil is faulty. The main argument, as i understood it, is the syllogism that the definition of a state is inherent within its opposite. That is, we assume that darkness is the absence of light. However, the syllogism is faulty in the sense that we presuppose our means of understanding the subject is inherently connected to the nature of the subject. In much easier terms to understand: We may have to come to understand and define darkness/falsehood/Evil through the absence of light/truth/Good, it does not neccessitate that the Existence of one in intangent to the other! Then again, that's just my two cents (from my obviously flawed intellect).
