Light or Darkness?

So... I completely agree with Saruman's post. The terms weren't properly defined... Does Darkness necessarily mean betrayal, and does Light necessarily mean altruism? Where do you put selfishness, calculation, and cynicism then? Is that Evil? No. It doesn't necessarily involve killing someone or doing something similar. You've taken what are essentially absolute concepts of Good and Evil and simply labeled them Light and Darkness. I much prefer the interpretation of Light and Darkness in Lukyanenko's "Night Watch," even though I don't like that book. There, the Light ones are portrayed as altruists, and the Dark ones as egoists. I myself am closer to egoism. Of course, this doesn't mean that I think you should never help another person, but constantly doing so at your own expense, if the request isn't very important, doesn't seem very wise to me. And if you take absolutes, it turns out that you either only do bad things, or you only do good things, sometimes at your own expense. Although, of course, there's the opinion that good deeds are eventually rewarded. Well... if everyone thought that way, maybe that's how it would be. I can't say which I lean towards more. I'm doing fine with egoism; I think I know when to disregard my own benefit and when not to. I've done both good and bad things for people, and honestly, even realizing that I did something bad, I didn't regret it afterward. Maybe I thought I was right at the time. So, I'm definitely not a saint, but I'm probably not the worst person either.
Also, I believe that in this matter, not everything depends on choice, especially if a person is inherently dark, so to speak; changing for the better, if they manage it at all, will be extremely difficult. It all depends on what's inherent in a person. If a person is kind, then it's certainly easier to change for the worse, but still, who would do that out of dislike?
And don't confuse philosophical Light and Darkness with physical light and darkness. The only thing that's better about light is that the human eye can distinguish things in it, but sometimes you just want to sit in the dark.
