What? No it's not. It's the exact opposite. You're the one doing the attacking when you torture someone.To say that torture itself is evil is kind of like saying that to kill another person in self-defense who is trying to kill you is evil and therefore man shouldn't defend himself.
Do you understand what the word possibility means? With that argument I would be justified in torturing you right now, because you might know something. That's insane.The possibility of obtaining information which can save the child's life certainly does justify it and I don't see how it will be made worse.
You're missing my point.Past deeds certainly are justified by present outcomes.
I'm not. I'm assuming there's always other options. If you can get the information from someone by torturing him, you can also get it by offering him something he wants.We are assuming that torture is the only way to save the child's life. And you have to choose to torture this man to save the child's life or not torture him and let the child die.
...if there is a reasonable possibilty that this man knows something it is worth it to torture him.
It certainly is effective in my opinion, it is simply common sense that if a man knows something and refuses to reveal it and this information is vital to the security of the lives of the citizens of your country then if he refuses to reveal it willingly then the only option is to force him to reveal it against his will by inflicting pain on him.
