She's probably not a sociopath -most likely has Borderline Personality Disorder. That's the most common disorder described on this board. Sometimes narcissism accompanies that, but the hallmark is the emotional instability and moodiness that can look like bipolar, but isn't. People with narcissistic and borderline personality disorders lack empathy, but that doesn't make them sociopaths - just very focused on themselves and their own needs, and unable to see things from another person's perspective.

You can them go from normal to crazy in like two seconds. 
The Bigger point is if there nuts. They are nuts.  You can play the lable game.  And it is a game because there no real test. It's like is it a cold or flu ??  If you answer a d f. Yes it's this.   Most of the time you can't do anything.  We all see on the movies and TV   These people get treated and better.  That not true in life, either they are smart and have control to cover it up  or they are on the streets. 
 

I believe Spawn is a Narc/ASPD. My friend told me one time that Spawn and her daughter were talking and Spawn told the daughter she loves to lie because she's good at it and people believe her. Spawn was 16 at the time and that sent chills down my spine to know she was that cold and calculated. When she posted on social media that she would like to "purge me" I believed her and lived in actual fear. Spawn has a lot of Meth Mouth in her, and Meth Mouth was the kind of crazy that you just never know what they might do. I mean crap Meth Mouth showed up at her exes house, broke down the door and beat him with a tire iron all because their son said his dad took him to get ice cream.

She has extreme victim mentality, blames other for anything that goes wrong, but then will brag about the dumbest things as huge accomplishments.  She is extremely self absorbed and doesn't care about the feelings of others.

All Sociopaths are narcisissts but not all narcissists are sociopaths.

sociopath = narcissist + 

parasitic lifestyle

chronic irresponsibility 

failure to fulfill obligations

pathological lying

criminality

duping delight

recklessness

Ex's daughter has MANY of these traits...I think she has BPD: 

Her friendships are intense but short lived.

She binge drinks, and indulges in high risk sexual behaviour. 

Moods are very volatile

Has that irrational fear of abandonment.. when Daddee dates a woman, she "is losing him" 

Extremely jealous and possessive

Flies off the handle at things others would see as trivial.

OSD is histrionic personality DO. Similar to BPD except she is more like a chameleon. 

- Presents as charming, fun loving, charismatic

- over sexualized and uses that to gain attention. Requires constant attention and to always be the center of attention.

- can function in school and most likely employment but lacks the skills to be successful.

- is completely self-involved she cannot see outside of herself, her wants. She lacks empathy.

- she does not have a personality of her own. She takes on the personality and interests of whomever she is trying to have a relationship with.

- is a compulsive liar, who convinces herself her lies are true . Will end a relationship or become enraged if her faults or lies are pointed out to her. 

- everything bad that happens to her is someone else's fault. 

- she has a ready made excuse for everything. 

As far as BM goes, I am not sure exactly which personality DO she has I refuse to interact her with long enough to truly find out. She seems more BPD as she gets enjoyment from playing the victim. 

Started at 12 SD walking around with all her goods hanging out, posting soft porn of herself on social media. 

He was an honor student until the work started to get hard and she would actually have to apply herself, she won't because that takes away from her social media time. 

It's ok her grades are poor it's because she is depressed. 

It's not her fault she got black out drunk. Her friends made her do it and then just blamed her so they wouldn't get in trouble with Thier parents. 

OMG this all resonates!! 

Ex SD: 

Walks around the house in ultra tight pants, with low cut tops...

At her cousins wedding wore a skin tight dress, plunging neckline, slit up the thigh... when my sister saw the family group photo, she asked "who's the hooker photo bombing??" LOL 

Every thing that has ever gone wrong in her life is NEVER her fault. Got that? NEVER!!  

Failure to get jobs is the interview panel fault... they were all assholes. 

Daddee doesn't give her support, doesn't understand her, never has her back, bla bla bla 

When she failed her licence, it wasn't her fault, it was the testing officers fault because he was an asshole...

I agree....I believe my ex sd is a narcissist.  She was spoiled with no correction growing up...permissive parents who worshipped her more than the other two triplets ( the other way to create a narc is severe abuse). My first husband is a narc, so her games were familiar.  

No empathy for anyone. If she deems you 'did her wrong' (like asking her to pick her thongs up out of common areas) she was a victim and you are now part of her flying monkey circle of smear campaign. Drama. Manipulative. 

And everyone, including incestuous daddeee worships this helpless 23 yo. Sooo sad ppl live this way. I didn't need another narc in my life or a husband who worships her n throws me under the bus. He even said to me, her name is Isabella. Only her friends call her Issy. Well, I don't want to be part of the Issy club.

But the parents created this narcissist. If you worship a child they turn into one. 

Neither Issy nor her dad will ever know real love. Narcissism isn't curable. So she will never know deep feelings or connections. He won't either because he has made her his god.

I used to think SO's daughter was a psychopath.  I really don't know what she is.  She's extremely manipulative, lies constantly, cons people (including teachers), was somehow an honor student but read and wrote on about a 4th grade level in Sr high.  Failed out first semester in college.  No fear of the law because the rules don't apply to her so has been arrested several times for drug dealing and forging and cashing checks...always gets out of it basically. Drug addiction issues.  All about instant gratification.  No friends except one poor individual who she drops like a bad habit when something better comes along.  Turns on people in a heartbeat.  Always a victim.  When she got pregnant that wasn't her fault, she was a victim of an unplanned pregnancy {{eye roll}}.  Didn't have a full time job until her mid 20's.  Totally delusional, thinks everything should be given to her because she's special.  Punishes her father by withholding her attention until he does what she wants.

I blame it all on poor parenting and her father having guilty daddy syndrome .  He claims she has anxiety...poor thing...

In large part because I did not want to propegate my condition or saddle children with it, or their children with it.

So, why would adults with psychological, behavioral, or emotional illnesses have children?

Sounds selfish, self agrandizing, and wrong to me.

My DW has a cousin (her BioDad's Brother's daughter's daughter) who sadly was abused and neglected as a child.  She is hell bent on breeding her own herd of unconditional love minions. Not for her to love unconditionally, but to love her unconditionally.

People like these toxic mentally/emotionally/behaviorally ill BioParents and the breeding for unconditional love abused child/adults are the poster children for requiring a license to breed.  They have no business breeding and propegating their crap.

smh

My mom once told me, when I was in my anxty teen years, that we all inherit baggage from our parents. That baggage becomes our  issues to resolve.  People who do not resolve their own issues, have no business having children.

IMHO of course.

What I have found to be JUST as bad as BPD is SDs and BMs having the "victim" mentality. You cannot say ANYTHING to either of them without them getting extremely defensive. They both have the mindset of "me vs. the world". They think everyone is working against them (almost paranoia even). SD receives constructive criticism about an assignment from her teacher... she bursts into tears to DH "She just hates me and wants to make me feel bad!!!" Um, no. Your teacher is trying to help. But you take everything SO personally, no one can say ANYTHING to you. I worry how she will EVER hold a job since she can't have anyone correct her. Also, plays the blame game. When she does something wrong, it is always someone else's fault or someone "made her do it". I can't stand people with this mindset!!!

"Perfect" parents do not raise shitty children.  I also believe that personality disorders, develomental disorders, phsychological disorders are no excuse for shitty behaviors and parents of kids with these issues owe their children and broader society the responsibility of raising these kids with clear standards of behavior and performance.

Tolerating crappy kid behavior, regardless of developmental issues, etc....,  is failing as a parent.

IMHO of course.
