Good and evil are constructs in the realms of morals and ethics, which are also constructs produced by society. And so on. If you continue delving into these constructs, you will discover that the only ultimate truth is your firsthand emotional, physical, and mental experience.
Yes, you can map these manifestations to those end-of-the-chain constructs, but does it make them true or real? Or are they merely your personal, fuzzy classifications based on your experience and programming?
Viewed from this perspective, there is neither evil nor good indeed.
