Why would someone do things to hurt people on purpose, and then play the victim when they are called out about it?

[Anonymous]

Someone I know is a bully and tries to hurt people or wear them down on purpose. She does this repetitively. People recently stood up to her about what she'd done and her bullying and she started crying and denied she did those things (she told multiple lies to cover it up.) Why is she now playing the victim?

I hate people like that! My sister was the same way growing up. She's 5 years older than me and always bullied me. My mother believed her precious daughter could never do anything like that. She would turn it around on me then start crying my mother comforting her and me just standing there after she beat me up. But somehow it was always my fault.

Narcissist and Sociopaths do that
