Brigid,
"Good" and "evil" are conceptual abstracts that differ from mind to mind.
What seems like meaningful and important intellectualizing on life's deeper questions, is really just a ruse. It's just more of the mind thinking a "self" into reality, as it weaves an identity out of gathered beliefs, judgments, questions, assumptions and other concepts.
Do you want to find the answer to life's conundrums? You won't find it in the mind. Investigate instead within the silent pool of present moment reality and the most intimate senses of being and existing. Who/what, are you, really?
Discover your true-identity, and all else will fall into place.
