Task: Question Answering
Input (English): Passage: The opening scene is set at a wild teenage party in a small apartment. The kids suddenly turn against everything around them and trash the apartment to complete annihilation. The kids are called "Destruction Incorporated", a bunch of self-imposed derelicts who terrorize a sleepy Florida town. They are led by the near-psychotic Dexter, his pal Denny, Denny's girlfriend Bitsy, and their friend Lummox. Their reason for forming this so-called "destruction crew" is as Dexter states: "just for the hell of it."
Dexter, Denny, Bitsy, and Lummox stop at a local neighborhood bar for a few drinks when the bartender becomes irritated with their shenanigans and orders them to be quiet to which they respond by beating up the owner. Afterwards, Dexter and a few of the Destruction crew pile into Dexter's 1967 white Mustang car and drive around town terrorizing and harassing the locals. One teenybopper steals a lady's newspaper and sets fire to it. A man is splashed painted when a few other youths throw paint at him. Also, a police officer is contemptuously taunted.
At a corner coffee shop, the overly zealous teens engage in a bloody fist fight with another teenager, named Doug, who used to know Dexter and was part of his gang before walking away years ago. As result of the rumble, the group begins to trash the place. The proprietor threatens to call the police, but is cut short when one of the teenyboppers punches him in the face. Dexter and Denny, aided by other Destruction crew, cruelly drag the owner to the stove and they unmercifully burn his hands on the hot stove. 
Question: Why did Dexter say Destruction Incorporated came to be?
Output (English): just for the hell of it.
