Some torture a needed life-saving tool

I completely agree with Mirko Bagaric in his article “Some torture a needed life-saving tool.”  I believe torture is needed sometimes as long as it is helping to save the lives of innocent people.  It is only okay to torture if you are doing it to someone who is “evil” and is planning on killing many innocent lives.  If you cannot get the information to save these lives without the use of torture then you must do anything to get what you need out of this horrible person.  This “evil” person is torturing people anyway by killing them just for his own benefit.  If there is a terrorist and you need to find out where their next attack is going to be then go ahead and torture them until you have gotten the information that you need to stop it.  It is not okay though to just torture for the sake of torturing someone.  If you are just doing it for your own sick pleasure then it is completely wrong to do.  If you are not getting any information that saves lives from the person you are torturing then you should not be doing it.  Once you have gotten everything you need from that person you should stop the torture.  Torture can help to save many lives.  Those who are torturing in order to save lives are doing the right thing and should continue to do so.  Many people have tortured terrorists and have successfully stopped attacks and have saved very many lives.
