Yeah I agree with both points. Also I read that he was a long term Trump supporter long before he ran for president.
And treating these malignant narcissists with kid gloves is useless I agree. But they are obsessed with their image, with their false ego or mirror image. So he will read how he has seen. This is of course speculation and I'm not a psychologist, but that is what I think happened to Musk. He played this image of a good tech "captain of industry", then when he got rejected because of his greed and lies he switched to a different persona. And there is no real persona. You can even see similar things with Trump, very far back he was a democrat / liberal, but these malignant narcissists don't have a real personal.
Not sure how useful any of this is really. In the end we live in the age of monsters. And they are all across the political mainstream spectrum now.
