TL;DR; Narcissistic emotionally stunted manchild acts out to get attention because he can't figure out why he isn't getting the respect or adoration he clearly deserves.

And any attention is better than none.

Im not sure that's all idiocy though.

It's certainly a large helping of narcissism and hubris.

Nepo-lucking your way up enough to mingle with the other amoral arseholes probably requires some skill of a kind.

It could just be trolling, he's certainly rich enough and that gives him a layer of protection in the current capitalist societal structure that's thick enough he can pretty much just be a 24/7 dick and there will be zero effective consequences.

I personally think he's got in to a position where he can have basically whatever he wants except the things he actually would like to have.

He's a boring, lonely, sad child of middling intellect and can't figure out why the things he does doesn't get him the things he needs/wants.

So he escalates, and lashes out, because he can and its his only form of communication.

Like a crying toddler with big feelings, they can't articulate the problem so they cry and scream until someone else figures they need food and a hug.

Except his tantrums kill people and ruin lives.

If he was an idiot that might go a ways to explaining the continual inability to just not be a dick to everyone, all the time.

But I think it's worse than that, i think he's choosing to continue being a dick, as a way of proving to himself he still has an effect on the world , not the respect, acceptance or adoration he wants, but still, something.
