Good and evil.

I agree. Although it has already been said that there is no such thing as absolute Good and Evil, that these are rather philosophical concepts, and one cannot exist without the other. The entire universe is built on the eternal conflict of these opposites.
I am very interested in one question (exclusively from a philosophical point of view): Is war Good or Evil? For me, the answer is obvious... But is it always a manifestation of evil, violence, and a kind of expression of "love for one's neighbor"? How can we reconcile this with the assertion that there is neither pure Good nor absolute Evil?
