They never experience a relationship of mutual respect, unity, and commitment. They never know what it feels like to love someone more than themselves. They inevitably destroy that which loves them. They are never able to just be themselves. They have to lie about themselves, to themselves and others, just to get through a single day. They can never be by just themselves, content for any single moment. They can never understand the epiphany of what it is like to submit to a greater power (God), because in their mind, there is no greater power other than themselves. They do not learn to better themselves after each failed relationship, only ever repeating their cyclical spiral of doom again and again. Everything in their life is superficial, they never ever reach any deep philosophical understanding, about themselves, others, the world nor the multiverse, all they know is the shallowness of the world that directly orbits themselves. When their physical body fails and all that is left is their non corporeal soul, it will be but an empty soul, weighted down by a lifetime of sins; dishonesty, cheating, betrayal, cruelty, theft and more. That soul will one day need to learn all about those sins, from the receiving end, so that it may advance, as every soul inevitably does.
Who’s to say, might a victim of a narcissist once had been a narcissist themselves. Who knows.
All I know is that the narcissist no longer has me in her life, and that is karma enough for me.
