Lucifer was not evil.
God gives man what he needs. Lucifer wanted to give man what he wants. Lucifer challenged God proposing that Man would worship him for giving him man he wants, rather than God giving him what he needs.
God gave man ‘free will’. The problem is that man chooses the wrong things, the evil things, the bad things, the things that appeal to the senses, the lust, the desire for power and control over others. The DEVIL in is man, not Lucifer.
The result (as described in theological literature) is that man is turning away from GOD (what he needs) and turning to EVIL (what he wants).
It is all up to us. When enough turn away from God, then we will see what most would call ‘the end of the (civilized) world’. Not because GOD will do something to us, but because we will have done it to ourselves.
Thanks for posting the article/link.
P.S. And as PAUL HARVEY pointed out, we are already way down that road.
