I think my sister (14, but very soon 15) is a narcissistic psychopath (medically)

I think my sister who is 15 is a sociopath/psychopath

I think my sister has aspd and npd and I know no one in my family will believe me

I believe my 15 year old sister has aspd

So first, I’m aware she can’t get diagnosed with aspd and only conduct disorder, but I still believe she’s genuinely has aspd and will get diagnosed at 18

So first, she has no childhood trauma, atleast not any im aware of, and she was actually highly empathetic right before puberty. After hitting puberty she didn’t seem fully cold (I believe she’s masking, she still seems to have empathy but if you pay close attention you realize she has none) but you could still see she’s faking it. She has stole from her school (went in bags or just took items) because it was fun and like a game for her at 11, she vandalized the school bathroom with Nazi slogans and slurs at 13, wrote some edgy note in her computer about how she wants her classmates to get tortured to death, engages in life risking activities (I don’t think she knows she is capable of dying), skipped class, and she doesn’t get along with her peers. Additionally, recently when her brother cut his palm open on a boat, she seemed to be so unremarkably calm and went into the room her brother was in just to secretly take her iPad and phone and then never checked up on him again (she did ask how was he when we came up to her and more but she doesn’t actually care, she also ran to take her soda drinks before going to the hospital with him). She is comfortable joking about his hand injury and it gets passed off cuz she’s like “one of the guys” but I genuinely think she has aspd. She has also admitted she sometimes imagines our mom killing herself to make herself cry. I’ve never seen her feel any actual empathy, ever cry for someone, ever feel remorse or guilt, she constantly lies about herself to others for no reason or to get empathy/make herself seem cool, and there isn’t a single person in the world she doesn’t shit talk behind their back. She gets angry so easily at our mom, my mom yesterday went to a clothing store and she immediately started getting angry because she didn’t go to a store for stationaries and she ALWAYS does this, she never cares about anyone, if we do anything not the way she wants she will make sure to throw a tantrum. Additionally, no one would believe me because she masks so unbelievably well, she gets along with all of her teachers and is genuinely kind to them, everyone considers her exceptionally kind. Even the principal, who knows what kind of horrible shit she would write about her classmates and what kind of trouble she would get into, is friendly with her and greets her whenever he sees her (btw, a lot of the guys who also get suspended like her are never this friendly with the principal). She has thankfully stopped getting suspended, but it took her like 5 suspensions and I don’t think she feels guilt but is just smart enough to stop. Also she is a gifted child, exceptionally smart, without even studying which I think makes the school go more easy on her because the other people who get in trouble in school aren’t actually stupider than average and academically challenged. I think she may also have narcissistic personality disorder

What made me write this post is because I kinda felt she has no empathy but yesterday when she told me so calmly, with zero care in the world how “isn’t it crazy how our brother could have hit an artery and just died immediately” (even our mom pointed this out)

But the thing is, nobody even dares say “hey, maybe she’s a little sociopathic,” like my parents still view her as an extremely empathetic angel even after this repeated behavior of getting in trouble with school and signs of zero empathy. Like my mom keeps saying to her (used to, she stopped the suspension stuff for one year, god knows if she’ll start again) I know this isn’t your real self but maybe it fucking is
