Have you ever met a child psychopath?

There's some debate about whether psychopaths are born like that or made as a consequence of their environment/upbringing. If they are born that way (which I believe they are) have you ever met one? What were the signs?

I say this because there is a child in my wider family who I think may be a psychopath, there has been signs from when he was very very young and as he moves through his teenage years things have only got worse. I can't get on board with it being an environment thing as no one else in the family behaves the way he does, it's quite terrifying to think that no matter what you do your child could still go on to do horrific things and not feel a jot of guilt.

What do you think? Are they born or made?

So do you think there's a switch that flicks on their 18th birthday and they're suddenly a psychopath?

No it means they can't be diagnosed with psychopathy

I taught a child once with very high intelligence but no empathy at all, and apparently no fear or care about consequences. If you held any kind of boundary, he would attack you, adult or child, or break something he knew was valuable. We frequently had to evacuate the classroom because he would get dangerous.

His parents were worse than useless. He was suspended once for attacking my TA. About half an hour later, he walked back into class. He said his Dad had dropped him off and somehow he'd bypassed security and just strolled back in. He said his Dad took him to a coffee shop, bought him a cookie and a juice, then brought him back.

The school was just as bad. They refused to send him home again and said that I would have to "internally exclude" him, which meant sending him to be taught 1-2-1 by the TA who had a bite mark and a large bruise where he'd kicked her.

I sent him to the head of year for deliberately destroying another child's work, she sent him back with a sticker and a lollipop.

The other children would freeze or curl up into a ball when they saw him approaching them. If they had a toy or book he wanted they would just immediately hand it over and hope that it was enough to avoid them getting hit.

I don't know whether he was a psychopath but he was heading that way and it was being facilitated by everyone around him.

Only one, Robert Thompson. The other was possibly slightly neglected but not in any obviously traumatising way. And as I said above, it's the latter, Jon Venables, whose behaviour seems to have remained dangerous to others. (Or else Thompson is just cleverer at keeping below the radar - but I suspect it's not that. I think Thompson responded well to the education and treatment he got while in young offenders, and Venables did not.)

Thompson said at his last parole hearing that whilst he regrets that the murder took place, he acknowledges that his life in prison and the education he got there was far better than it would have been had he stayed at home.

Venables wasn't a simple case and he definitely wasn't from a wealthy background, although not as poor as Thompson's. He had a very low IQ and mental health problems which remained untreated. Unfortunately, it seems that whatever is broken inside him can't be mended.

Agreed (except that I didn't say he came from a wealthy background - nor indeed do I believe that wealth would have been a determining factor)

The difference I see is that Venables came from a "normal", relatively structured background - the sort of imperfect but adequate family that many many children experience who grow up to be functional human beings: Thompson OTOH was clearly deeply traumatised by his abusive family.

I think the lesson I'm drawing from that (if one can draw a general conclusion from one case, however extreme) is that children who are going "bad" as a result of trauma can be "saved" from that destiny fairly reliably, given enough resources - which of course most don't get sadly, as this was a truly exceptional case - but that there are also children who are just "different", whose bad behaviour is more innate. And for those children, changing their behaviour is far more complex. Might even just help them learn to manipulate better!

The definition of psychopathy is a combination of grandiose narcissism + lack of empathy/remorse + lack of taking personal responsibility or long term planning.

I am surprised at the 'lack of long term planning' criteria.
I would have thought that psychopaths with enough intelligence could make long term plans e.g. over a year, to achieve their personal goals.

It isn't referring to that, it's referring more of a pattern of impulsive behaviour with a lack of regard to the consequences or taking responsibility for them.

The pattern of stewing and planning revenge is a different aspect, I think.

MistressoftheDarkSide · 18/05/2026 15:01

The question of manipulation skills is an interesting one as to a degree society is built on it. We all operate to some level on the concept of risk versus reward, and societal / cultural / religious / spiritual influence are big driving factors in that.

Most people (I probably naively hope) confine "manipulation" to achieving benign outcomes for all concerned, at least on a surface or obvious level. Manipulation and subterfuge to feed malevolent urges without apparent conscience are terrifying, and aside from immediate undesirable consequences, psycholigical fall out in victims is huge, such as the genuine gas-lighting that can be perpetrated by individuals and authoratative institutions.

Loss of trust and faith is difficult to come back from, and the second guessing is exhausting, as having been fooled, even once, leaves one questioning ones own intelligence and creates a perpetual defensive outlook. It's horrible to have to accept that yes, there are some people who don't give two hoots about your feelings or the negative impact on your life, and if the experience is replicated in other circumstances, it's hard work not viewing new people or situations with suspicion.

In current times I'm struck by how many experiences I and my friends have had with very calculated wolves in sheeps clothing, who have done some dreadful things in terms of breaking trust. Interestingly a good number have EUPD diagnoses, and even when they have been supported despite their actions, it is clear they cannot easily stop themselves. I have immense sympathy for them, but at some point they move onto new friend groups because too many boundaries are crossed, and the complications become above the average persons paygrade, so distance feels like the safer option.

It's sad and tragic for all concerned, but as to the question of whether there is any element of psychopathy or sociopathy involved has never been established, as they do appear to demonstrate remorse and desire to change, can be charming, and yes, manipulative in damaging ways.

I am adopted ( adopted at 8 weeks old )
I have a biological sister and she was brought up by our biological parents I didn’t meet her until I was in my late teens early twenties.

I had a very nice , you could say privileged upbringing
My parents were very law abiding and very good people. we lived in a nice house in a nice area.
They weren’t really rich but we never went without anything and I had no trauma in my upbringing . Big extended family around holidays abroad paid for driving lessons and got me my first car .

However despite having a very normal
upbringing I will bend and break rules if I think it’s ok with my own set of morals . I have very little problem in lying if I want something .
i have a horrible horrible temper which scares me sometimes but I rarely lose my temper as I’ve learned to control it over the years . But I can hold a grudge against someone for years

I have no problems in wishing ill on people I don’t like either .
Someone I knew from my school days died recently and honestly I felt quite happy when I was told ( I know that’s not normal ) but she was a bully in school to lots of people and I just felt glad she was dead and I know her death was most likely quite painful . My immediate thought when I was told was serves her right .

But i don’t really like people that much and have no problems with cutting people off completely .
I have never smoked, done drugs and i am
an occasional drinker never been in trouble with the police .
Got straight A in school ( many years ago )
I have been happily married for over 25 years

my biological sister id the complete opposite grown up with a drunk and mentally ill mother and a father who had other kids and didn’t really want to deal with a kid that had “issues”

smoking at a early age led to drugs and drinking , and crime she’s been in and out of prison many times once for 8 years and both her kids have been in and out of the care system for pretty much all of their lives . She’s also been sectioned twice last I heard .

she would take and do anything if she thinks she entitled to it and not give a shit if she was to physically hurt someone

whereas I would think hard about the consequences and if I can get away with it 😂. 😂
I will conform to rules & laws if I need to get something but otherwise I’m quite happy doing what I want
I absolutely hate hate being told No or what to do by anyone.
Years ago an optician told me I couldn’t wear contact lens again gave me such a feeling of rage towards him I felt like hitting with the paperweight on his desk 😂

But i think my sister is just the bad side of me and that if I hadn’t been adopted i would have been just like her as I can see so much of myself in her especially looking back when I was a teenager and a bit wild .
but I think because I had a very stable and loving upbringing that nasty side of me didn’t develop as much

I don’t have anything to do with her anymore as there was a period many years ago where she was incredibly vile towards me and my family because she didn’t have what I had growing up ( her words not mine )

Both of us can be very charming and sociable if we need to be . And surprisingly people seem to like us both .
I have never had a problem making friends but I tend to get bored very quickly of people
I’m quite happy with my own company

This is one of the most interesting contributions to the thread. Terrific example of what others have mentioned, how you can be born with certain things in your nature but the way you're brought up and the experiences you have can make a huge difference to how your personality and character develop. The BBC Horizon documentary about James Fallon, mentioned umpteen times early in the thread, showed that very well.

No one has ever met a child psychopath, because being under 18 is an exclusion criteria for the assessment of psychopathy.

Children's brains are not fully developed. They cannot be psychopaths.

I work in a school, you are very wrong. There are definitely child psychopaths, they just aren't diagnosed and their behavior usually excused.

jcsc · 18/05/2026 18:18

its my personal belief that they are born that way and they lack empathy no matter how much you work with them and provide help. That’s just my opinion though.

Some children are predisposed to psychopathy due to their genes.

Their environment is another key factor so no doubt normally functioning people can spot children who are exhibiting behaviours outside the social norms who may later be classed as psychopaths.

Yeah this is true. Theres the case of Paris Bennett who murdered his 4 year old sister when he was 13. He did it to hurt his mother who wasn’t giving him enough attention. He’s now a diagnosed psychopath.
what I found fascinating about it is his grandmother (his mums mum) tried to kill her grandfather when the mum was a child. She was also subsequently diagnosed as a physcopath. So clearly there’s a genetic link.

Unforgettablefire · 18/05/2026 18:29

I grew up with one. Not a sibling but a family member.
He was a horrible kid, tried to kill animals by strangling them, pushed his sibling down the stairs when he was a baby in his pram. Just weird and cruel for absolutely no reason but pleasure.
Killed an animal as an adult. No remorse or empathy for anyone or anything so I don’t know if that makes them a sociopath or a psychopath but the rest of the family are all ok, and there’s no childhood trauma or anything to put it down to. Just an evil kid and an evil adult.
Just because a diagnosis hasn’t been made doesn’t mean it’s not there.

DilettanteRedRagger · 18/05/2026 18:29

People can stop mentioning that they don’t diagnose psychopathy before age 18. Based on what we now know about people, that needs to be drastically reconsidered. You will only get someone the help they need when they’re diagnosed, and they should be diagnosed as soon as they begin to need help. You need diagnosis to start at the age of criminal responsibility. That’s the age at which society accepts mistakes are no long accidental. If they’re not psychopaths and just misguided, they’ll have grown out of it by then. If that means you need to reconsider the whole “incarceration” system so it focus on rehabilitation and reintegration for both children and adults, that’s no bad thing.

Yes I went to school with one….

Yes I briefly worked for one who was appointed as my Team Leader… I got a role in another Team as I had seen him in action within six weeks!

Absolutely correct. They are few and far between but like autusm, there are different degrees of psychopathy. Some is fuelled by trauma and some children are born like it. Not all psychopaths are equal and society needs them to make those difficult decisions in government, business etc. Take for instance Andy McNabb and Theodore Roosevelt who are both confirmed as high functioning psycopaths and take/took decision that others couldn't make because empathy clouds judgement in some situations. I've encountered traumatised children who develop in such a way to protect themselves from further trauma on many occasions. The brain adapts to the circumstances a developing child finds itself in. Then there are those born without the emotional chip or moral compass that most people develop as they grow up. Some may have developed this way through nature others through nuture or lack of it Some people never harm others even though they have no empathy for another living being. Its complex and no two paychopaths are created equal. Many people have quite obvious markers, others not so much but then it depends on the testing and who's doing it. Many variables come into play when talking about diagnosing psychopathy. Some experts rely on the dark triad as a place to start but the same starting points can be equally attributed to trauma e.g., animal cruelty, bed wetting and fire starting. Diagnosis is not an exact science but they do walk amongst us. Psychopathy exists on a spectrum with only 1-2% of the population being true psychopaths in terms of filling in those boxes on an assessment test and crossing over to the dark side officially.

GlosGirl82 · 18/05/2026 18:36

Listen to the Podcast RedHanded - they talk about this a lot - there are lots of early signs and you may find it helpful to identify them. Many of the sighs are found in people who go onto commit crimes and high functioning (and totally lovely/non-criminal) doctors, lawyers, bankers etc. it’s about desensitising towards feelings and outcomes…

Loley22 · 18/05/2026 18:51

As others have said under 18s cant be diagnosed. There are some conditions that people say are a precursor under 18

Should have said he now has a working diagnosis of psychopathy.
The diagnosis was given once he was an adult, but the behaviour was there from him being a toddler.

It's not a diagnosis any more. It's out dated. It doesn't exist in current diagnostic manuals.

The nearest thing is severe personality disorder with a dissociality trait.

There's an environmental component but like most things it's not as simplistic as made or born - the interaction is complex (for example an attachment disorder in very early childhood could be the result of neglect but can have much more complex origins, say when a child is incredibly ill from birth for many months and parents are unable to cope, and adoption even by fantastic parents can't always meditate the trauma of early neonatal separation and trauma in utero - this can interact with genetics).

Nobody can be diagnosed as a psychopath because it isn't a diagnosis any more - the same way Asperger's syndrome isn't diagnosed any more, multiple personality disorder isn't diagnosed any more, hysteria isn't diagnosed any more, neurosis isn't diagnosed any more...

Very true, but still very much used in forensics for specific presentations of ASPD rightly or wrongly.

HRTQueen · 18/05/2026 19:11

No

I have met children who’s behaviour is very anti social and most likely on their way to being diagnosed with Anti Social Personality Disorder

I believe it’s more nurture than nature, having worked with a number of men diagnosed with ASPD and men who rated highly of the psychopathy test not one of them had a stable secure upbringing

and often what looks to be on the outside isn’t

and they also don’t fit the popular ideas of being charming, obviously manipulative, intelligent aspects of their personalities are as varied as the rest of the population
