I did not address the ‘good versus evil’ because I tend to agree with what was posted before — that those are terms created & used by humanity to ‘describe’ desired behaviors.
Good, evil, time, hope, faith, love…
…there are many ‘terms’ which are nothing more than agreed upon parameters or conditions. Most (or nearly all) are still more ‘mind constructs’ than actual ‘things’.
For example… MIND.
We have brains… odd 3 pound globs of jello (filled with fluid and neurons, and neat stuff)… but we have yet to find where MIND is. Most ‘think’ it must be in the head/brain… but no one can confirm or deny it.
As for ‘PURE’ good or evil…
I confess I believe that people can ‘act’ with good or evil intention. Some ‘acts’ of nastiness lean toward VERY evil. I guess I’ve led a sheltered life since I have never had to face / experience TRUE evil
or for that matter ‘PURE good’. Once experienced, I will have to re-evaluate my view of ‘how stuff works’ in MY world.
