The Fighter

Picture a human, stripped of an established society, without the common sense of justice, of right and wrong, one without a moral code. One that follows no rules - save from the pre-programmed base animal instincts:

Survival: Eat, Drink, Sleep and Copulate.

Picture then this form brought up in the wrong society, one that abuses its body, torments its mind and destroys its spirit. The product: a caged animal in human form, just as dangerous and born into the single desire to kill other humans.
