Should I ignore it?

So I'm asking for advice cause I'm unable to decide about things on my own lol.. So there is this one friend of mine that is acting kinda weird and im curious if I should just ignore it.. So basically she is thinking she is a psychopath. Like she just admits it and tells me that she worries that she could be a psychopath but she also uses it as flex. She is very proud of herself when someone calls her psycho even as a joke- Also, she thinks that CUZ SHE DID A FUCKING QUIZ-
But you know she wasn't a threat or anything..I mean she wasn't till she told me she could hurt me but nOt NoW. Like am I supposted to take it as a joke? And she said it twice..She is in my friend group, but others take her ''OoH I'M SuCh a PsyCho'' as a joke.. But she doesn't.. And once when I almost died she said it was funny to her. She also said it was funny when her cousin's friend commited suicide. I get it some people react that way because of stress but she seemed proud of it. Of course I told her it's not something she should be proud of. Are psychopaths that stupid to just admit it to your whole friend group and be weirdly proud of it? Is this something to ignore?
