Sadist??

So my friend is 16 and in the 11th grade, we were watching a movie in class with a rape scene in it, obviously the teacher mentioned that we are gonna skip it and my teacher also stated “what will we gain from seeing someone lose their dignity” my friend under her breath, stated “pleasure” and then she said aww but I wanna watch the rape scene. She then claimed she was just joking, but I don’t think she was. On multiple occasions she’s just said and done things that a sadist would do. She also gets in trouble with the law, steals, lies, has sold drugs. She’s also set fire to things and set off small fire works behind school property. She doesn’t get caught tho, since she’s an amazing liar and I can’t lie she is intelligent. She’s also mean but acts super charming, she is also good looking, I think she’s a psychopathic sadist, I think she likes hurting certain people for the fun of it. Oh and she seems to be a little promiscuous. Do any of u know what she might be??

UPDATE: so I might of had sex with her, umm I feel even more attached now. I just can’t un friend her like u guys are suggesting...she’s hot...I got turned on...great sex...yeah😬
