Humans are the masters of horror! Sick minds are alive and well in Mexico. Well, sick minds are alive and well wherever humans reside, but let's focus on Mexico.
Mexico is really into cockfighting. Cockfighting is for the sick minded who love the sight of blood. Lots of blood.
Cockfighting is a "sport" that involves two roosters fighting to the death in an arena. Those who enjoy this sort of gore place bets on which rooster will win the fight.
Sometimes, to increase the blood letting, metal spurs are attached to the legs of the roosters to increase the amount damage inflicted.
According to the Humane Society of the United States (HSUS), those metal spurs have punctured the lungs of roosters and pierced their eyes. Even owners have been killed from an accidental slash from the metal spurs, which is a nice of Karma in my opinion.
Spectators, subhumans indeed, place bets on the rooster they feel will win the fight. Many of those who are spectators at cockfighting events are involved in drug dealing, selling of illegal guns, and murder. These low-life individuals have a great deal of money on hand to place bets. Commit more crime, and the money for cockfighting is a sure thing.
The roosters involved in cockfighting never get to retire from this disgusting "sport." They just get to be dead.
