Although I haven't really had time to keep posting here, I have to respond to this topic.
Torture is never justifiable, ever. You can throw around that crap about it working better, about it "saving" lives, and that it is a good technique for getting answers.
Torture is about one thing and one thing only, vengeance, it is not about saving lives, or protecting people, it's about revenge, and making someone suffer for the things they may have done. It is a premature, infantile, and pathetic attempt to control a situation we feel is out of our control.
When I was young, there was a much older kid that took a toy of mine, he was taller and he stood over me and hung it above my head so I couldn't get it. I finally got so mad I leaped on him and started pounding on him. I got my toy back, but what did I achieve from hitting him, I made myself angry, I probably humiliated him, and I could of gotten my toy back my asking nicely, or telling my mother.
Some people will say that my analogy is off scale. That I'm putting into a conversation a comparison that isn't even comparable. But it is.
Why is it?... One reason... the moment I put my hands on him, I lost the right to consider myself as being on the right side. I was young, and the idea of right and wrong were blurry at best. But I was still able to consider myself as being justified in beating him up.
Are any of you five years old? No you aren't, you are older, people that consider themselves beyond that childish emotion and instinct. But the moment you decide to use that primitive way of control, you lost whatever claim you had to being justified.
Now let us say the police suspect that a person has planted a bomb in a heavily populated building.
Is torturing him justified? No, it isn't. It is morally wrong, there is a possibility that the suspect is innocent, and there is no guarantee that any information you get from him will be correct, he could stall you until the bomb goes off, then he goes to prison, and you don't torture him.
Here are two quotes from Gandhi that explain my point of view. "I object to violence because when it appears to do good, the good is only temporary; the evil it does is permanent."
And, "Victory attained by violence is tantamount to a defeat, for it is momentary."
Wow, torture doesn't look so great now eh?
