Karen is an Angsty Sue

I learned something today: My character Karen is an "Angsty Sue".
Definition (according to Wikipedia, on the page that speaks of "Mary-Sue"): Designates a character tortured to the excess, and/or whose horror of the past borders the ridicule, and contrasts with that of the other characters of the work. Common clichés: murder, rape, child abuse or neglect, orphan status, etc. Parents are rarely spared. By the overload of the pathos, the character is supposed to acquire the sympathy of the reader; He can be depressed, constantly abhorred by everything around him, or obsessed with a bloodthirsty vengeance. Stereotypically, if the character bears a heavy guilt (sometimes completely unjustified), the story will in fact reveal a detail hitherto unknown of the facts that will absolve him of any ethical regret. On the contrary, if he has no guilt about his actions, he will impose his vision of things without the slightest remorse or interrogation, crushing all his opponents in his passage (whether they are right or not). In any case, it is usually a romantic relationship with another character who will "save" him and bring him happiness. It is often a distorted distortion of the Byronic hero.
