Torture has been a common element to warfare since man started fighting each other. Sure, it is an unpleasant thought and a worse reality, but what part of war IS pleasant? Every aspect of War I am aware of is ugly and brutish. Why? Because War is an abomination. However, I do recognize the need for War. War, is as many say, the last resort. They say that because of how horrible it is but also with the recognition that at some point, people have to engage in hostilities with one another for some reason. And what happens when men engage other men in battle? One side tries to win and men die. And when it is a kill-or-be-killed situation, which it is in War, then it is better to be judged by twelve than be carried by six. And it's that way because loss or failure could result with the annihilation of your people and most certainly your life. So, men engaged in warfare with other men, in the interest of self-preservatoin and your people winning the war, the employment of certain methods can gain information vital to their cause and detrimental to their enemies. What generally happens when one side receives intelligence vital to their effort is lives are saved and an advantage over the enemy is gained which could result in the loss or failure of said enemy. So while torture is despicable, it is a necessary tactic men use to win battles and stay alive.
