That or he’s badly abused/neglected, and is in need of very serious therapy.
My wife’s hometown of like 300 people had a school shooter, and the kid was one of the worst abuse cases I’d ever heard. Tortured, made to live in a closet and eat dog food, shit like that. Ended up shooting the principal while wrestling for the gun (his only victim) and the principal was like the only guy in town who brought the kid food and clothes and stuff (which his parents then “punished” him for receiving). Just an awful situation.
In some ways, this kid acting out so early may save his and others lives, fucked up as it is.
