Give examples of how a person does bad things knowingly and recklessly.

Bad deeds deliberately: teenagers painted the walls of the school from a spray can with obscene words, broke a bench at a public transport stop, cut out inscriptions in the passenger compartment of a bus or trolleybus with a sharp object, with a knife, damage to a playground, high school students take money away from elementary school children.
Through negligence: threw a stone, accidentally hit a girl, slipped in the dining room, broke dishes, did not notice a pedestrian on a dark road, driving a faulty car.
