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?

If anyone is a Law and Order SVU fan this storyline will be familiar. Obviously I know it's just fiction but it's a very good portrayal.

Tell that to Jamie Bulgers mother

Exaxtly this- and a lot of people who go on to murder when they are adults display sadistic behaviour as children towards younger weaker children and animals. Also in America shootings in schools are ofter carried out by children.

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 a very interesting post, thanks

Well your softly, softly.approach did nothing for John venables, who manipulated every 'professional' and went on to be a sex offender.

What other approach is there for 10 year old kids?

Robert Thompson had a terrible home life. There was sexual abuse in the home. In his police interviews, he got really distressed about things like the mess that ‘come’ made.

I don’t think trying to understand why someone has murdered a child is ‘soft’. Do you think psychology and the study of human behaviour is ‘soft’?

Meadowfinch · 18/05/2026 03:32

Ds' childminder had cared for children for 34 years and in that time, she said, there was only one child she genuinely feared what they would do in the future.
Her description was "completely unpredictable, very bright, charming or violent at the flick of a switch, could not be left alone with other children, enjoyed inflicting pain"

The child was in her care for 5 months and she said was the only child she had ever chosen to end the contract. 🙁

MulberryFresser · 18/05/2026 04:47

I surprisingly haven’t met any but retrospectively, I can see how some adults I knew behaved nastily as kids. You meet people who knew them growing up and they paint a picture. One guy - his mum invited me along to a family therapy session so that I could learn not to hang out with him anymore.

MulberryFresser · 18/05/2026 04:48

A friend of mine works in forensic CAMHS and she has 15 guys like the Southport killer on her caseload at any one time. I’ll ask her what they diagnose them as because they are under 18. She can’t predict which one will kill.

JMSA · 18/05/2026 04:58

I work in the nurture base of a secondary school (Scotland).
I work regularly with two boys who are well on their way.

Annoymo · 18/05/2026 05:20

Yes I agree you can see tendencies in them. I know one - my niece. Even as a young child very manipulative, lies and no empathy when others were upset or hurting. An adult now and it’s very clear. Her mum ( my sister) always tells people she’s BP but it’s obvious she’s a psychopath. I do believe at a young age g age you can tell even as they are developing into adults. It’s fully to assume only when they turn 18 can you diagnose them.

ProudCat · 18/05/2026 05:44

Yes. I'm a teacher who worked for nearly a decade in psychiatry before retraining.

if you are worried about some of these behaviours you should contact national police ACT Early Support Line at tel:0800 011 3764 0800 011 3764 in confidence. This is for children at risk of being radicalised but also children who may be hyper focused on causing harm to others.

People can be psychopaths and live by the letter of the law and not harm others. So although I'd lean toward psychopathy being nature, I think how someone acts will come down to nurture. If someone has no empathy or emotion but is taught that there are severe consequences for causing harm to others but they could have a nice life if they abide by social norms, they can live a normal life and people won't have a clue what they actually are. So I would say nurture plays a very big role in it.
There will be people with other MH issues such as schizophrenia or ND conditions like ADHD that can cause people to harm others through delusional beliefs or impulsive behaviour and poor emotional regulation, I'd be more inclined to believe their behaviour is more based on nature than a psychopaths behaviour is.

Most psychopaths are in fact like this. It’s extremely rare for them to murder or intentionally hurt someone. The majority live normal lives. A lot of people with psychopathic traits are in top management positions, also surgeons, lawyers, policing, military, sales etc. Basically jobs where you have to stay extremely calm under pressure OR manipulate people.

TheGreatDownandOut · 17/05/2026 16:48

I believe they are born rather than become that way through their environment. I’ve read a few books on this topic as I find it fascinating! My understanding is that their environment can shape the way that psychopathy presents itself. So some will go on to be violent criminals, some will become CEOs and politicians 🙃

ITA! That sums it up quite well. A variety of factors go into whether the child grows up to be a success in business or politics versus a Ted Bundy/Charles Manson.

I believe that whereas a percentage of a child's behaviour is down to inherent personality most of it is due to how the child is treated and their education and upbringing.
A lot of the children I come across behave in an appalling way - absolutely no consideration for other people, selfish, totally dismissive of adults and generally unpleasant and no sense of decency or right or wrong. And I am convinced that is not because they are in inherently bad. They have just been given no moral guidance. They take the norms of behaviour from what they see on social media and no adult seems capable of challenging them.

Where do you come across so many children who behave awfully? Yes, children are selfish - but in my experience the vast majority of children definitely have a sense of decency and right and wrong. Your post makes me wonder how you can have such a different experience.

Makemeinvisible · 18/05/2026 08:13

@GreenChameleon
When I first moved to my present home nearly 6 years ago I was warned about the local children by a long term resident.
I didn't believe her. But unfortunately she wasn't exaggerating.
They have made my life hell at times. I'm an older woman who lives alone and socially isolated so seen as fair game. I try not to let my experience cloud my opinion of ALL children but it's hard not to be wary.

My son has an innate lack of empathy. He is autistic and doesn’t even understand why you would care how someone else feels.

he’s never gone around killing small animals though or hurting other people. In fact his college tutors describe him as being “a really nice boy” and if he’s mean to you, you deserve it.

I believe, with few exceptions that psychopaths are made. Those two boys that killed Jamie burger came from very neglectful and abusive homes. Many people do come from homes like this and don’t murder but they don’t have functioning relationships either.

A friend works with a boy who has suffered extreme neglect and abuse. He’s already committed violent acts and those around him are fairly certain that he will almost certainly kill at some point. His mother just hopes it’s her! I guess her feeling is that at least the rest of the world will be safe from him 🤷‍♀️

How does your theory about psychopaths being made not born account for the large numbers of psychopaths from good homes with stable upbringings, who go on to lead 'successful' lives as businessmen etc. ?

People just want to believe that they are ‘made’ by society, so they can indulge in the fantasy that they can be eradicated by changing society. If everyone had a good upbringing, then rape/murder/violence wouldn’t exist (god i wish i was this naive)

The situation you describe with your sister is like a scientific experiment - the impact of nurture.

In don’t think a lot of what you describe would qualify as a psychopath though

So do you think you’re a psychopath?

I disagree, Id say that sounds like textbook psychopathy. The only psychopath I know was a surgeon, actually a really good one. He was pretty good company as long as you didn't expect anything from him and I wouldn't have wanted a personal relationship with him. He couldn't really sustain relationships of any kind, you amused him for a while then he'd get bored and move on.

Every time there's an 'I'm a psychopath - AMA!' thread on here, the poster always just sounds like someone who says 'I'm mad, me!' and bangs on about how much they hate small talk. Heavy adult goth vibes.

I work with adults with severe mental illness, many of which have also committed terrible crimes and/or have diagnoses of personality disorders. IME, true psychopathy-that is, the inherent inability to feel empathy for others due to a neurological defect-is incredibly rare. I’ve been in this field a long time and I don’t think I’ve actually ever met one. Everybody else is a combination of neurodivergence, trauma, deprivation, poor parenting, poor education, mental illness, drug use and desperation. That doesn’t mean they’re not responsible for their actions. Except for the most seriously mentally unwell, they knew what they were doing and should be held to account-but psychopaths they are not. Just sad, desperate flawed humans. Often thoroughly unpleasant and criminal people but not evil.

So the conclusion to draw, based on your experience, is that psychopaths are unlikely to experience mental illness. (Note that psychopathy is a neurodivergence or personality disorder, not a mental illness).
Because the sample data for you is all people with mental illness.
