Search Results: crying over someone

There’s a backstory to this question.

My younger cousin who is a senior had a bit of drama today involving her on-and-off boyfriend (?), Nathan. Both are 18. They broke up at least 4 times over petty things and dated people in between their breaks. Anyway, Nathan dated this girl who was a sophomore (Patty) and they broke up for whatever reason so he went back to my cousin while Patty dated someone else. However, he would still flirt and being intimate with Patty and my cousin found out when Patty “confronted” her after she logged onto his messenger and read the conversation he had with my cousin. She was furious and broke down to her friends in tears. One of them in particular kind told her they told her so and informed her that the Patty was crying as she found out her boyfriend had cancer and my cousin said she didn’t give a fuck, which lead to her friends calling her fucked up for saying that and left it at, “I don’t care.”

She told me this at home and said she kind of felt wrong for saying she didn’t care about someone having cancer but at the same time said she thinks the girl is lying for attention (which she allegedly famous for), didn’t know him and had no connection to him so she didn’t understand why she SHOULD have to care. I didn’t know what to say. Obviously, she said it out of anger and frustration but do you think it’s wrong to not care about someone else’s misfortune or at least not be sympathetic towards it in general.

Both of us are now adults (she's now 20 and I'm 24) and we're spending more time together. I've always wondered if her diagnosis at the time was accurate. She was diagnosed with conduct disorder with psychopathic tendencies and institutionalized at age 10. Then she was released 6 years later.

She was detained for serious bodily harm and torture on 2 younger boys, arson and several animal cruelty charges. However, given these things about her was she really psychopathic?
- She did cared about her friend in crime at the time. That's the only friend she had and sometimes referred to her as a sister. She's an only child.
- She explained how she once wanted to be good when spending the weekends with her father but anger took over and hence the destructive urges started again.
- She only bullied and beat smaller, younger boys, not girls. I'm guessing this was her displacement anger towards drunk pedophiles that molested and more than likely raped her too.
- She was crying in the interrogation room, threwing herself towards her father (not the mother) for comfort and requesting to go back home.
- She currently expressed full remorse for her actions back then and they do seemed genuine.

From the looks of it, that doesn't sound like someone psychopathic. It looks like a former angry, abused, troubled girl. She still had the ability to bond and empathasize. Even if it was very limited, that's different than if someone had ZERO abilily to bond/emphasize. That means she wasn't psychopathic.
I'm not a psychologist but if getting helped rehabilitated her then she doesn't fit the category of a psychopath. A true born psychopath wouldn't bond with anyone and no amount of therapy would fix them. They wouldn't be expressing remorse either. What do you think?
