I think there's a cycle. I don't beleive in a "Final Victory" for good, evil, or neutral.
Before I continue let me clarify my beleifs, to make the rest of my argument easier to follow, cuz i tend to confuse people a lot:
1) I beleive that good, evil, and neutrality all exist. I also beleive that a LACK of good, evil, or neutrality can also exist in specific instances.
2) I beleive that anything that goes against our natural desire to unify is evil/bad. I beleive that all Social Creatures, especially human beings, are born with the urge to not only "fit in" but be with someone, i do not belevie that anyone truly likes to be alone, or truly likes to be in conflict.
3) Ergo, i beleive that Conflict is ultamately a result of our inability to see past fears, differences, and biases and failure to Unify. This is not to suggest that Conflict is avoidable, or that disunity is ALL our faults. Circumstances are sometimes stronger than choice.
4) Finally, I beleive that Ultamate Evils to be those of inflicting Murder, Torture, or Control over another person. To me, these 3 are the top.
Okay, having stated that:
Although I do not respect Evil, or its possible "role" in any balance, I do beleive that it is undeniably a part of our existance, and not something that we are capable of erradicating, only limitting.
It seems to me there are cycles of good and bad, i.e. periods of peace and war, periods of pleasure and pain, periods of understanding and ignorance, etc.etc.etc.
As "good" as things can get (for example the raising of social equality and civil rights) things can get JUST as bad, if not worse (the rise of hurricanes and effects of global warming). I beleive the same goes for people. I beleive that people use up peace and violence, that people use up unity and disunity.
Once people start taking unity for granted, they start giving in to the pleasures of harming another person and feeling superior. Once people realize how destructive, harmful, and pointless disunity is, they try going back to achieving unity, and then back to disunity, and again and again....we as a human race need to mature lol
