And since it's just some big nebulous energy thing, how would it have the same ideas of 'good' and 'evil' that we do? It would just sense that sometimes some folk use its power to shoot lightning while others who use it don't. All it should be aware of is that it is being used by some people for a variety of things.
If the Force evolved to perceive an imbalance between the good and evil activities in the cosmos as "bad" the way an ameoba perceives something hot as "bad," then the Force might act to repair the imbalance by doing something to increase the amount of evil in the cosmos.
This is different from the Force not liking evil; the Force does "like" evil, when it perceives there's too little of it. (What it actually perceives is the imbalance.) So that solves the problem of the Force having moral judgments but no consciousness. The Force really doesn't understand the difference between good and evil, or that evil is bad for most of those little critters scuttering around the universe.
I still question how the Force could evolve like an ameoba. There's no selection pressure and natural selection for something that's not a species, so how did this situation come about? That's why I think the Force must have "always been this way."
