What you're describing about these people and lack of humility? It's the reason you see so many Cluster B personality disorders. They are only focused on themselves and can only define things by how someone/something makes them feel. They can't see anything by way of reason. Like that lady in the hair salon... "You are evil because your kindness made me feel bad. You made me feel bad on purpose."
This is the way Borderlines and Narcissists think.

The New Age lie, is the same lie Satan fed Eve in the garden. "You shall be like God".
Pride took us down and ultimately it will be what takes many to Hell. These people don't know what real Love & Light is, they can't! They are too busy worshipping themselves as "divine". "You are God" is Satan's biggest gaslight on the world. It's the same thing that got him thrown out of heaven.

Romans 1
18 But God shows his anger from heaven against all sinful, wicked people who suppress the truth by their wickedness.
19 They know the truth about God because he has made it obvious to them. 20 For ever since the world was created, people have seen the earth and sky. Through everything God made, they can clearly see his invisible qualities-his eternal power and divine nature. So they have no excuse for not knowing God. 21 Yes, they knew God, but they wouldn't worship him as God or even give him thanks. And they began to think up foolish ideas of what God was like. As a result, their minds became dark and confused. 22 Claiming to be wise, they instead became utter fools.
