bear baiting, guillotines, public castration disemboweling and dismemberment as entertainment, the inquisition, the crusades, Christians fed to lions, christians burned for fun, Saint Bartholomew's Day Massacre, viking pillagers, sending boat loads of drunken convicts to Australia, the holocaust, the Irish troubles, US anti european immigration laws circa early 1900, children as factory workers, the black plague as a result of being indescribably filthy, Roman conquest, WWI, WWII, rape of Berlin, Rape of Stalingrad, etc.
