Most people today think of chaos as just another word for confusion, and they have strong aversions to confusion. Thus to them, chaos seems bad. However, there is a subtle difference between chaos and confusion. Confusion suggests a situation where things are jumbled together so that it is difficult to discriminate between the different elements in the mix.
Confusion is also a state of mind.
Chaos, in its common usage, implies a complete and irremediable lack of organization. So we can say that a confusion can be fixed while chaos is an entity unto itself. And while it is true that chaos is often thought of as disorder, it has a larger meaning. The word chaos originally meant an abyss or chasm. But the ancients knew, and now the most modern scientists know, that nothingness is an illusion.
