Psychiatrist Dr Varma Deyalsingh says a mix of social, psychological and biological factors can drive the extreme violence seen in some home invasions, as he addressed the issue during an appearance on CNC3’s The Morning Brew today.
He explained that while many offenders enter homes intending to steal, violence can escalate due to deeper emotional and social influences.
“When you’re doing a home invasion, sometimes it’s really a combination of personal history, environment, and opportunity,” he said. “It’s not just taking the belongings for monetary gains, but it’s to teach them a lesson, to show them.”
Deyalsingh said some offenders develop resentment towards perceived wealth or privilege, which can fuel aggression.
“Those persons have money… they are more privileged than me. So, some individuals are now developing that level of hate, that level of despise towards individuals,” he said, adding that acts of violence can also give offenders a sense of power and control.
He pointed to upbringing and social conditions as key contributors to criminal behaviour, saying children raised in environments marked by poverty, violence or instability may come to view crime as normal.
“A child grows up with a clean slate, but what that child sees, what that child experiences… will now create an individual, an adult, who may dislike society, who may hate authority,” he said.
He added that the absence of strong family structures, including parental attachment in early childhood, can affect emotional development.
“If a child doesn’t have an attachment figure within the first two to three years of life… that child… may end up with a little sort of a dislike, a disgust for society because their needs were not met,” he said.
Deyalsingh also referenced social learning, explaining that exposure to crime without consequences can reinforce criminal behaviour. “If my community shows me that… people are committing crimes and getting away… I learn that probably crime is beneficial,” he said.
He said early warning signs can include school dropouts, lack of role models and behavioural issues in children, such as harming others, cruelty to animals or persistent rule-breaking. These, he explained, may point to conduct disorders or antisocial personality traits.
Addressing the impact of violent crime on children, Deyalsingh warned that witnessing traumatic events, such as the killing of a parent, can have lasting psychological effects.
He referred to what he described as the “Batman syndrome,” where trauma can shape a child’s worldview and behaviour. While support services exist, he said more long-term intervention is needed.
“A child could witness that trauma, go into depression, have that stress, have post-traumatic stress… tracking them throughout their adulthood is something we have to do,” he said.
Deyalsingh also raised concerns about what he described as growing desensitisation to violence in society, noting that frequent exposure can lead people to normalise crime.
“People who may have exposure to violence… to them, that’s a way of life,” he said. “The numbness is there because… it’s happening so often. Once it’s not happening to me or my family, I accept it.”
He warned that this detachment can weaken empathy and reduce willingness to assist victims, as individuals prioritise their own safety.
