There is always some good, and some evil in all situations. To get what I mean; if you sit still and do as little as possible (while maintaining consciousness, like deep meditation for example), you are doing good by not doing bad, but doing bad by not doing good. Whether something (an action for example) is more good than evil (which could be the motivation for the action, dependant upon the causer of that action seeking to do mostly good or vise versa) or vise versa, depends upon what that something is, the environment in which it is in, and the way in which it's being "viewed" (which, of course, can be through one or more "veils" (Tom Robbins speaks truth) of structured thought, which could end up being the deciding factor).
So, whether an action is good or evil depends upon the entire history of structured existence (infinite?) before the action, interacting with the chaotic present of the action. Although, in "reality" (is this reality?) there are no exact anythings, such as time, so the difference between the time infinitely close to the action and the time of the action occurring is non-existent (how long is a moment?).
This also means that structure and chaos are also only just ideas, as are good and evil. They both refer to our understanding/awareness of existence continuing to exist, to grow and thrive, and the opposite. But then, opposites don't exist, and neither to perfect "clones"; always some gray area in between.
Another way to see this is the debate over "free will" vs "destiny", it is always a bit of both, sometimes it's more the case that you have a choice, sometimes it's not, of course, following this logic (if wanted) that argument in itself (as well as this one... etc.) is sometimes more true, and not... etc.
