As police arrested two psychopathic killers for sexually abusing and murdering several children in Noida, an upscale suburban town on the outskirts of the national capital, experts say these serial slayers have no remorse but get sadistic pleasure by such acts.
"Serial killers cannot be considered as normal people any way. They are sadists and have no remorse for their brutal acts," says leading psychologist Aroona Broota.
"After the initial hiccups they tend to get pleasure in their acts without even bothering about the victims or about their reputation. They are certainly not successful people and a deep feeling of frustration drives them," Broota said.
On Friday, police arrested businessman Moninder Singh and his domestic help Surendra Kohli alias Satish for killing several children after sexually assaulting them.
On Friday and Saturday, skeletons of several children kept in bags were found near a water tank in the Nithari village in Noida. A total of 38 children, most of them minor girls, have been missing in the area for the past two years.
Maxwell Pereira, a former joint commissioner of Delhi Police, said the chilling manner in which the killers executed the crime speaks volumes of the strange circumstances and their mental frame.
"It becomes just a compulsive habit to kill once the initial fear and queasiness following the first killing is over. This renders them fit material for criminologists, psychoanalysts and social scientists to study," says Pereira.
It is the second such instance in the past three months in the national capital region, when police have arrested serial killers.
In November, a gang of seven people was arrested who had killed around 35 people since January 2006 in and around Gurgaon, another suburban boomtown and an outsourcing destination.
Before they were arrested, these people used to offer a lift to people waiting on lonely roads and later kill them inside the cab.
"It's a result of utter frustration. Here children, women and lonely people become easy targets because they can be easily be overpowered either for money or sexual satisfaction. They get pleasure by killing others," says Sameer Parekh, a noted psychiatrist.
People too agree with what the experts say.
"A normal human being cannot take so many lives. They are either medically unfit or simply butchers. Its really pathetic to know that children were killed in cold blood for no reason at all," says Ajit Patra, a resident of Noida.
"It's absolutely inhuman and the criminals should be awarded death penalty. Police officials who have neglected their duty too need to be punished."
