Is torture ever acceptable?

Armed with the knowledge that their suspect has planted three nuclear bombs in three U.S. cities, black ops interrogator H (Samuel L. Jackson) and FBI Agent Helen Brody (Carrie-Anne Moss) resort to extreme methods to get the confession that could save millions of innocent lives. A former nuclear expert, Younger (Michael Sheen) has turned against his country. Shortly after Younger plants his bombs, he's apprehended by the nation's top anti-terrorism task force. But while Younger is in custody, the FBI can't get him to reveal where the nukes have been hidden. H may be able to get an answer, but once Agent Brody gets a glimpse of his tactics, she begins to wonder whether the good guys have finally stooped to the level of the terrorists, or if H is truly justified in fighting fire with fire. That was the summary of the film ' unthinkable ' that I've seen before, in this film the interrogator H uses all type of torture against the nuclear expert who refuse to tell them the place where he has planted the bombs. Even all FBI agents didn't accept that because the criminal is also a human and the human soul is a very valuable thing but H knows very well that torture will the only way to avoid the death of millions of innocent people. I think that torture is not acceptable because as Carrie-Anne and the other FBI agents thought that we should know that we are all human beings, but sometimes against criminal, I think that we should use and implement all torture techniques to save life of innocent humans.
