Psychology: vandalism

Self-tutoring about psychology: the tutor mentions some ideas he read concerning the motivation behind vandalism.

Vandals, it seems, often target useful installations in places they frequent.

Painting a drawing on a wall might seem relatively benign, since the wall maintains its function. However, what about vandalism of an installation such as a bus seat, sports facility, or public restroom? What might motivate such behaviour, given that the vandals may likely be among those who use said facility, and therefore may suffer if it’s not replaced?

Decades ago, I went to a big-city school in which some washroom stalls didn’t have doors. They’d been ripped off by vandals, then never replaced. There wasn’t a mirror in the washroom, either, for a similar reason. Did either alteration benefit its perpetrator?

I read herein that vandalism with no apparent reward is believed to have perhaps two motivations. One is defiance against a much larger system in which the perpetrator feels trapped. The other is for the perpetrator to showcase their ability to carry out grandiose acts.
