What a narcissist does those he or she slanders.
One of the tricks of the dramatic fiction-writing trade is to know, and focus on, a particular aspect of human nature. It is this: Every person's most precious possession is the image of him- or her-self that each carries around inside. Fact: People will do ANYTHING to preserve and protect it. Fact: Nobody can bear to have that be the image of an evil person.
This is why character assassination is the fate worse than death. That's why it's called "destroying" a person. This is why it drives people to murder and suicide. Even criminals who have committed violent crimes treasure a self concept of themselves as essentially good inside. And many, perhaps even most, are.
Storytellers exploit this by creating a situation in which the hero's self-concept is threatened. That's automatic maximum motivation. For example, Hamlet's self concept is that of an honorable man. So Shakespeare has his father's brother come along and seduce his mother, murder his father the king, and then stain the throne of Denmark with an incestuous marriage to his mother in order to keep the throne from going to Prince Hamlet as it should.
What are people going to think of Hamlet if he goes along with this? If he just looks the other way at the murder of his own father? What is Hamlet going to think of himself? But it's a Catch-22, because everyone else is sucking up to the usurper, so they dishonestly view Hamlet as crazy for suspecting the usurper and will condemn him as evil for doing justice. So, Hamlet is damned as a bad person either way. If you put a character like Hamlet in a predicament like this, you have yourself a whopper of a story with it's own engine roaring and ready to go.
Since before recorded history, there have been stories of ghosts. According to legend, not just anyone who dies could become a ghost. A ghost was someone who could not rest in peace. He could not accept what had happened to him. Usually that's because he was murdered in some diabolical way, either as Hamlet's father was or as Jesus of Nazareth was -- by being framed and executed for crimes he never committed. He died a criminal.
Put yourself in his shoes. Could you tolerate that? No. Nobody can. Nobody can tolerate the whole world believing they're evil when they're not, especially when the person who has falsely accused them is the evil one and comes out smelling like a rose. That turns the whole world upside down, making good evil and evil good. It is an INTOLERABLE state of affairs! Human nature cannot abide it.
Indeed, even the blessed spirits in Heaven are said to be unable to stand it. For, that's precisely what started the mythical war in Heaven between St. Michael the Archangel and Lucifer, who later became known as Satan (which means the "accuser" or "character assassin").
That's the reasoning upon which is founded the belief that Jesus will return. The early Christians expected him to return to Jerusalem any day, with an army of angels.
Do you think that he would have been in a good mood?
They didn't. What do you think Pontius Pilate, the Sanhedron, and the people of Jerusalem would have done? Yes, the "innocent" bystanders of Jerusalem -- who mobbed Jesus one day as a saint and went along with his character assassination and murder the next by crying "Crucify him!"
Who did they think they were fooling? Me? I'd know I hadn't fooled him, and I be scared shitless of anybody I did that to. So, what would you do if someone you had done that to returned returned with great power? Tremble, eh?
That's why the traditional representations of the Second Coming are of it as "a day of wrath, a dreadful day." In this upside down world Jesus is the bad guy and the Sanhedrin and the people of Jerusalem are the good guys. Like St. Michael the Archangel, he is going to turn the world right-side up again by giving the real bad guys the reputation they deserve.
You needn't be a Christian to get the import of this story. The narcissist plays the part of the Sanhedrin (which was indeed narcissistic and envious of Jesus). The people of Jerusalem play the part of everyone who listens to his slander and calumny of you, even though it flies in face of the facts of your known conduct, gobbling it up just because it's juicy and because condemning others makes them feel righteous. If, say, this happens in the workplace, Pontius Pilate plays the part of the boss.
There is nothing worse you can do to a human being.
So, if this has happened to you, your feelings are natural. Don't make it worse by feeling guilty about them and trying to bury them. You cannot accept it. But you can accept your feelings. So do. You just hunger and thirst for justice. What's so bad about that?
If you bide your time, maybe someday you'll get it. But unfortunately, you probably won't, because there's very little true justice in this world. That place has been diseased and corrupted by the malignant influence of the narcissist. So just leave it, and kick its dust from your feet as unfit habitation for decent people.
Indeed, would you rather trade places with them? He owns them. He doesn't own you.
And there is karma. That's why I referred to that Clint Eastwood movie yesterday. I think it was High Plains Drifter. In a cloud (of dust) he descends upon a Jerusalem named "Hell" one day and agrees to help them defend against the "return" of somebody they did that to.
Boy! does he give it to 'em good!
