From August 2016:

How the toxic psychodrama of Trump's family of origin plays out in his relationship with his followers -- and what it means for America https://link.medium.com/TbixzomgK7 

"Fred Trump called his favorite son a “king” and a “killer.” Names that parents call their children are powerful: they convey parental feelings, hopes and expectations, helping to shape a child’s character and thus his future.

In Donny’s case, they primed him for his apparent character defect, that of narcissistic psychopathy, something he is proud of and the main reason for his political appeal today.

Trumpism is all about rageful revenge, & that revenge is achieved through winning. But it's not just ordinary winning, of the kind that makes the winners happy, proud, & satisfied, & maybe even benevolent toward the losers. Winning with Trump comes at a price--for the winners--

--and he is not shy about making it known:

"Gonna win so much people will say we can’t take it anymore."

"We’re going to win, win, win! We’re going to win so much, you’re going to get sick and tired of it. You’re going to say “Mr. President, we can’t take it anymore."

"My father used to say, “Son, you are are too tough.” (…) My father was great. (…) Folks, we’re gonna start winning again. We gonna win so much. You’re gonna be so sick of me, you’re gonna have the justice call me, you’re gonna have the lieutenant governor and the governor...

...call me and say, “Mr. President, the people of NC are sick and tired of winning! You are winning too much! They’re really starting to dislike you, Mr. President.” And I’m gonna tell the justice, and I’m gonna tell the governor and the lieutenant governor, “I’m sorry, but...

...we’ve gotta keep winning, because we’re gonna make America great again.”’

Trumpian Victory™ is then obviously as much a promise as it is a threat, because what kind of winning guarantees to overwhelm the winners so much that they would be sickened and vanquished by it?

‘“Please, we don’t want to win that much anymore, we can’t take it, Mr. President!” And I’m not going to care — we’re going to keep winning!”’

Does this not invoke an image of a torture victim begging his or her oppressor to stop? Or, more accurately perhaps, an abused child...

...asking his parent for mercy?

The parent, however, doesn't care: You are going to keep winning, no matter what! You’ll keep winning even if it destroys you.

This is what narcissistic parental abuse looks like, even as it's coached in the language of “It’s for your own good.”
