At least, in why Ishamael has such gloomy feelings about the DO. Eventually the DO will win, because the pattern keeps repeating itself...b/c it is a wheel lol. The DO has never gotten out of his prison so far, just been able to "peak" out. Otherwise he would have destroyed the pattern.

RJ leaves it unclear as to the exact nature of the DO. At times, he is clearly represented, at least in the eyes of the ppl of randland, as pure evil. That being from which evil flows and is derived. At others, he seems like a dialectic of the pattern's dichotomy.

Events surrounding the bore and throughout the series support this latter statement as well. The presence of a power, much like the one power, but not separated between male and female, represented a philosophical first for the aes sedai of the time. Everything in the world seemed to be separated into two categories, a dichotomy. Male, female. Light, dark. Good, bad. And so on and so forth. That's why the symbol of aes sedai is the yin yang symbol. This is RJ paying homage to that philosophy.

So detection of a power source free of dichotomy would be very interesting to the aes sedai of the AoL. It would be, in a way, like discovering a piece of God.

The DO also wants to break free of the pattern. He hates it, because of its dichotomous nature. At least, that's how it seems. The DO does not need our saidin and saidar to subsist. He is above and beyond the duality that governs our world and thus wants to destroy the pattern and break free.

Now, this would go against the feeling that the DO is pure evil and that the creator is pure good.

It's never really made clear to us the exact nature of the DO and the Creator. Something I find frustrating, but understandable.
