The usual set-up goes like this: the empath is forced to make a stand on seeing the sociopath say or do something underhand. The empath challenges the sociopath, who straight away throws others off the scent and shifts the blame on to the empath. The empath becomes an object of abuse when the apath corroborates the sociopath’s perspective.
The situation usually ends badly for the empath and sometimes also for the apath, if their conscience returns to haunt them or they later become an object of abuse themselves. But, frustratingly, the sociopath often goes scot free.
