The world's youngest serial killer (8 year-old killed 3 people) should this kid be locked up for life?

We already heard of the both the James Bulger case and Mary Bell. Those killers were ages 10-11 years old. However, this kid from India by the name of Amarjeet Sada (born in 1998) killed when he was younger than them. He was smiling at the police station and psychologist labeled him as a sadist that got pleased from inflicting injuries. He killed 3 people at the age of just 8 years old. Damn, just 8 years old.

He's a grown up by now and has been released from the detention home at age 16 and goes under a new identity. That's already a danger to society and we all know no one can come back to being normal after murdering someone, regardless of age.

Should that kid (younger than 10) get locked up for life?

Usually they start with animal cruelty at that age but that kid skipped to the chase and went to killing people. He chocked his 6 year-old cousin to death and then killed two other people, his sister and a baby.
