If you're implying they were corrupted because the Force exists and the Dark Side of it corrupts then yes, I agree.
How is it possible for you to then say this:
There absolutely is rejection. Jedi who adhere to the code do not turn into Dark Jedi. They turn into Dark Jedi when they reject the truths therein.
The Force is
both the "good" and the "bad" side. The "light" and the "dark". What Jedi do, what they've always done, is to reject the dark side completely, thinking and mistaking the light side for the whole Force. And since the Force has a will of its own, this is well established in Star Wars, it then corrects this Jedi deviation by corrupting some of them, bringing ruin to everyone.
This is why Kreia is correct. So long as the Force would be just an "energy that supports life everywhere" it wouldn't be a big deal. But it both has a will of its own and sentient beings can and do use it (and are used in return by the Force) for their own gains. The net result being a bloody trail across the galaxy, for suffering is far more strongly experienced than enjoyment.
The only winning move is to not play, in fact to cut off oneself fr the Force entirely for it appears that it isn't that essential for life after all.
