A big part of the polarity issue is that if you believe your own destruction is possible or even imminent (meaning that your consciousness could actually cease to exist), then things like values and integrity are effectively irrelevant except as tools for your continued survival. Such behavior is your choice of course, but it's a bit incongruent with the big picture of a fear-based belief system. You may in fact be hedging your bet, behaving a certain way just in case the universe doesn't work the way you think it does.
The idea of polarity is to commit fully to one type of reality or another, since in effect it cannot possibly be both. Either you're 100% unconditionally safe here, or you're not. There's no middle ground between 100% and not 100%. If you try to exist in the middle ground and hedge your bet, you're in no man's land -- you're guaranteed to have made a wrong choice because "maybe" isn't one of the options. If you polarize fully, you at least have a 50-50 chance of being correct, assuming both possibilities are equally likely, which is a lot better than a 0% chance if you don't polarize.
In terms of polarity, it's better to choose and risk being wrong than not choose and guarantee that you're wrong. Once you make this choice and fully commit to one path or the other, nothing will ever be the same again.
