@SterlingWright true, harm is done and cant be undone. The response to his apology from his victim said something along those lines. It affected her for a long time. Her self worth, her career, her time.

For the sake of argument surrounding narcissists, I feel that self loathing at least shows self reflection, recognizing they are a terrible person who has done harm. Can they truly be a narcissist then.

Its a moot point, whats done is done. Harm is done, sorry means nothing when its too late.
