Good and evil.

But is there really a line between good and evil? Show it to me then. I don't see where questionable good transitions into insignificant evil.
Besides, Draco said it well - "Who are the judges?". And from whose point of view should we consider it?

eXeCuToR, what I meant was that by asking this question, a person will never find an answer, will never start acting. "Who are the judges?", "What should we do?" and other such questions put a person in the position of Buridan's ass. Meaning, stuck between two haystacks. And while he contemplates which haystack is tastier and more appealing, someone more decisive, bolder, and not burdened by the ponderings of the Russian intellectual, takes what he wants, incidentally taking the ass with him (sorry for the rudeness, but isn't that how it is?).
Let's look at history: the intelligentsia (and we will consider it as the bearer of these questions) appeared with the penetration of the West into Russian cultural life (i.e., when theaters began to stage performances in the Western style, the upper class began to speak foreign languages, etc.) - this was the processing of our elite, its degeneration, because, having rejected Orthodoxy (Islam), the intelligentsia did not find anything to replace it with, and has been dangling in a suspended state between something and something else ever since. Hence these questions, which essentially mean the search for the meaning of life. Only these questions lead to a dead end, because they are amorphous, and there are more answers to them than haystacks. And each one is valid (in the sense that it is tasty).
That is why the question: "Who are the judges?" is harmful.
What to replace it with: there are two paths. The first is the Western one, let's call it the path of primacy, which does not think about anything, neither about good nor about evil, but performs actions based on what is more useful (while more useful for the body; the soul is an atavism).
The second path is religion and its various manifestations. Here, both good and evil are clear, defined (but at the same time, freedom of choice remains!).
Perhaps there is a third path. I don't know yet.

This is essentially what I meant when I spoke about the eternal question.
