New Delhi, July 31 (IANS): Need for instant gratification and not being able to take no for an answer have become the hallmark behaviours of the younger generation, leading to incidents like the fatal attack on a young JNU student by her classmate Wednesday, experts said.

"The lack of control over one's emotions is on the rise," psychiatrist Sameer Malhotra, head of the department of mental health and behavioural sciences at Max group of hospitals, told IANS.

He said the inability to accept "no" from others is a part of the general change in the milieu.

Noted psychiatrist Nikhil Raheja blamed it on the changed norms of parenting and upbringing. He pointed out that when children migrate from smaller towns to metropolitan cities like Delhi, "they are subjected to very little control (by parents)".

"This leads to them not realising the boundaries of relationships," he said. According to Raheja, parents are also spending less time with their children.

Malhotra also attributes the increasing number of violent incidents involving young people to their inability to manage anger.

"Sometimes people with personality disorders are more likely to commit such crimes," he said.

In a sensational campus crime, a student of Jawaharlal Nehru University walked into a classroom armed with an axe and a pistol Wednesday, asked a girl to walk out with him and, when she refused, drank poison and then slashed her with the axe.

He died while the girl is battling for her life.

In another such incident reported May 22, a jilted lover in Haryana's Karnal district attacked the family of the girl whom he wanted to marry, leading to the death of one person.

While the girl and her brother, Devender, sustained injuries in the attack, their aunt died of multiple stab injuries.
