Almost any antagonist from a Stephen King book / movie (excluding Kathy Bates in Misery, she rocked). More like the bullies in It, Stand By Me, Sometimes They Come Back, the nerdy guy in The Stand, or the religious characters from The Mist. Nostalgia Critic on thatguywiththeglasses.com goes over it pretty well in his reviews. Stephen King bullies / religious nuts are just crazy and sadistic for no apparent reason or motivation. In The Stand, we're supposed to assume the nerd builds a bomb and kills dozens of people because the devil's girlfriend blew him.
Another example might be some of the non-zombie from the original 1960s Night of the Living Dead. Rifftrax had a commentary on it as well. There's a lot of irrational behavior and yelling that feels unrealistic when cannibals lurk outside. It's thought that it's a commentary on racism, but the movie itself never addresses this and George Romero has said that they didn't cast the lead based on his race and that the role wasn't written necessarily for a black man.
