I think, good and evil do not exist as set things, but exist as matters of opinion.

If I consider something to be "Evil" And another person considers it to be good, what makes me right and them wrong? Nothing, nothing makes either of us right. it's all just down to what you yourself consider to be evil.

OP: In short: Only in a certain respects.

In even shorter: No.
