Same reason some kids want to be hall monitors. Some people just want to feel that they can project their will on other people. My guess is some deep seeded jealousy problems.

Some people are just assholes. They need to be told to fuck off, while the harsh language might a bit strong, it might also prompt enough of a serious conversation and prevent the growing toxic culture.

Actually no it's not a bit strong, those people need to be outright told to fuck off on a more frequent basis.
