Psychopaths

In addition to battling thousands of zombies, Frank West and Chuck Greene must also deal with psychopaths, humans who have either gone mad due to the zombie outbreak or are otherwise corrupt or evil, and who serve as the games' bosses. Examples include a clown who became insane after seeing his audience being eaten, a manager of a food market obsessed with keeping it clean and free of vandalism, a deranged butcher who thinks zombies are "spoiled meat" and humans are "fresh meat", an immoral sheriff who has taken advantage of the situation and executes survivors at will, and a French chef who went psycho after losing his chance for an interview to become famous.

While the term psychopath is used as an umbrella term for all of the games' bosses, most of these are simply immoral people. Only a few of them are actually driven mad by the outbreak (Adam, Bibi, Steven), most of them are simply corrupt people taking advantage of the situation (Jo Slade, The Convicts, Seymour Redding), others are simply overcautious (The Hall Family, Cletus). Brock Mason, in particular, is not mad nor immoral, but simply a soldier carrying out his orders. Likewise, Cletus was not driven mad by the outbreak, but simply has trust issues with humans and may also be unable to distinguish a zombie from a human.
