Tropes dealing with characters who don't get along with each other.
"Men often hate each other because they fear each other; they fear each other because they don't know each other; they don't know each other because they cannot communicate; they cannot communicate because they are separated."As the old saying goes, can't we all just get along? Since Humans Are the Real Monsters, this means that they all hate each others' guts, and that's one of the things to make a signature Crapsack World. Here are common tropes regarding characters who do not get along at all, or at least have some issues with each other. A super-index to Civil Unrest Tropes. Compare Hatred Tropes.
