Haven't read all the posts, but the defining feature of good vs. evil is the treatment of "innocents". If you harm innocents (intentionally and/or regularly), then you are evil. If you protect innocents (as much as you are able), then you are good. Neutral help those they care about and harm those that they hate, but generally don't step in one way or another to aid or harm random innocents.
So the question you have to ask is, are innocents being harmed by the deliberate actions of the being? If the answer is yes, they are evil. If the answer is no they are being helped, then the answer is they are good. If the answer is innocents are not being dealt with at all, then they are neutral. And remember, the answer to this is not what the being believes the answer is but what the universal forces know the answer to be.
