The truest form of chaotic is things happening without any known reason: completely and utterly unpredictable. It cannot be good or evil, because that would MAKE it predictable. Complete opposition to law and order would also not be the purest form of chaos, because that's yet another thing that can be used to predict its behaviour. Therefore, true chaos may align with law, then 'help' by growing trees, which are used to hang good people, then club evildoers with bodies.

Whilst doing the can-can.
