...RJ said that his world was "Manichaean". I'm not sure if he used the term properly; it's usually misused. Manichaeism said that there are two independent sources, but it always stressed that good was more powerful and would win when it deigned to stop letting evil run rampant in the world. What RJ seems to mean is that they are balanced and equal in power.

However, I still don't understand the whole point of evil. Let's say you're Satan. Let's say you didn't like the way God ran things. Do you really want to destroy all of Creation? Wouldn't you be dissatisfied with the result? Wouldn't you rather just let it keep going and enjoy it the way you do, tempting people to fail, to be petty, to hurt other people, to start wars, to abduct helpless little kids, to make hideous natural disasters, etc., and watch the reaction? It's a petty sort of thrill, but at least I can understand it in the way that I understand (but still get pissed off) when traffic slows down so people can look at the aftermath of an accident.

Shai'tan in RJ's world...well, that just doesn't make sense. Who is he GOING TO TALK TO WHEN HE KILLS EVERYONE? (I'm just imitating his style there)
