Maybe we aren't so far apart as we think we are, for we both give credance to Carl Jung for educating us as to Archtypes (he too studied Astrology)
and for that we are both grateful.
However, just to be on record here, as to the existence of "evil" I'd have to explain myself, (or feel I should explain), that some of the deeds done by those you point to (Night Stalker, Ted Bundy), etc. are so reprehensible that causes society to lock them up and throw away the key, and so they NEED to, protect society from those people, i.e. souls.
Yet, their soul still exists, the same as mine does.
The concept of Evil comes from seeing the dualistic world (in my opinion) in stark black and white terms, for Satan and the "evil one" has come down to us from time immemorable, yet does actually "have a beginning" in the ancient Hebrew texts as a concept and not a soul or a fallen angel. But this is "OT" to even get into.
I think it's a misnomer is what I'm trying to say here.
Not an actuality...but rather a "concept" to explain man's dirty deeds. (women's too), lol. Let's not leave them out. There are Black Widows galore in our society who "off their husbands" and even their children.
