Crusader

A crusader is someone who travels in search of something (perhaps leprechaun gold or the TV remote) but later finds out that it isn't there. After this occurs, they decide the best choice of action is to murder/rape the local peoples, later after mutilating the organs of the previously killed people, you find the very thing you came to find, plus you got to kill 50,000 people, good times for all (except for the mutilated corpses, of course!)
