(1) My traditional vision: "good" is what the herd desires, and means giving up on any reality-based plan in favor of human-based desires, feelings, judgments, etc. In this view, HAIL SATAN and kill the sheep.
(2) Evil is error, and like any other kind of error, it is what crushes us. What makes it a different kind of error is that it is a kind we should be able to understand and after a first experience, foresee, and thus avoid. The worst kind is Kantian "radical evil," which states that the mundane acts that the herd accepts are most likely to be the most evil.
At the back door the dog is MIA. Everyone else has dogs who go missing for days at a time. You push away the briefest thought of a cold lonely creature in a strange place wondering if its adopted human family actually gives a damn. The farthest thing from your mind is the mythological brightest of angels who rebelled against the cosmic order and so was granted his own greatest wish and greatest prison, independence in a dominion where he alone was law. Freedom in a cage. Cursing, you dump dog food into the bowl. It’s the dog’s fault for obstructing what you need to do.
The TV says today will be sunny but with a 30% chance of rain. Why can’t they all be sunny days, like the days in those car commercials (or antidepressant commercials) where people are happy together and spend more time on work-life balance than simply trying to make it through? Maybe science will fix it.
At this point, you take an important step: you obtain consent from yourself to get in the car, muddle through traffic to work, tolerate whatever stupidity occurs at work, achieve minimal results, and then come home to have a few hours of home time before you do it all again. You don’t want to, but this is the life everyone leads, trading time for a salary so you can be more like those people in the commercials and less like those under the bridges you drive past.

(3) "Good" and "evil" are both misnomers; there's only reality-based ideas and hypothetical ideas. This is essentially point of view #2 above, replacing any notion of inherent direction with the choice to avoid error (a concept central to nihilism).
