For sadists, making someone else grovel is not only the major way they secure a position of dominance in their relationships but also an activity they truly enjoy.
One reason people get manipulated is because commonly accepted psychological principles about why people do the things they do actually set a person up to be victimized!
Manipulators and other disturbed characters sometimes like to openly threaten or brow-beat someone else into giving-up or giving-in to their demands. They like to terrorize others into submission.
Disordered characters use the tactic of minimizing to manage the impression others have of them. It’s a way to manipulate others into thinking they’re not so bad despite the horrible things they’ve done.
Disordered characters are forever blaming their misbehavior on someone or something else, and skilled manipulators can make you think that somehow it’s your fault that they did whatever they did to hurt you.
