Yeah, in normal adult social circles if you behave like an asshole you get ignored and if you force others to put up with you you get kicked out and police is called if you refuse. If the social circle you are in doesn't kick assholes you find another one. But in school someone can just terrorize everyone else with impunity because people are usually not expelled, you can't easily choose a school that expels people and the abusers don't care about being ostracized or potentially expelled because they don't care about being in school in the first place.
