What if Keyes was Batman?

As I said in my last blog, Neff is not a cool person. So, I chose to look for other cool people that fit the same kind of detective archetype that Keyes fits. Almost immediately I thought of Batman from The Dark Knight. Throughout the entire film, Batman uses the powers of deduction and modern technology to track down both the Joker and the Falcone mob in the same way that Keyes uses wire taps to keep tabs on those who he thinks are committing insurance fraud. In addition, Batman likes to do most of his deduction alone in his temporary Bat-cave just as how Keyes investigates people from his secluded insurance office. Keyes and Batman also share a similar way of speaking to people. Aside from Batman's horribly raspy voice, both men speak with absolute authority regardless of who is talking to them. For example, Batman speaks to Commissioner Gordon as if he was a civilian just as Keyes speaks to his boss as if he was an insurance amateur. Strangely enough, both men also have a strong sense of compassion towards their guilty friends at the end of their movies. In The Dark Knight, Batman looks on the dead body of Harvey Dent and turns the attorney's face to the light as he decides to sacrifice his own reputation as a hero to make sure Dent's work is successful. Similarly, Keyes calls an ambulance and lights Neff's final cigarette in a show of justice and compassion for his friend turned criminal. Although Keyes does not go as far as sacrificing himself for the reputation of Neff, I believe that the factor in the situation that generates the coolness for both men is their compassion for their fallen friends.
In a final thought about Double Indemnity, I have begun to question why detectives are cool. Is it their skill in using deduction and intelligence that is appealing, or is it simply their determination in trying to bring justice to evil people? I am curious to see why others believe why detectives are cool, but I believe that Neff's apparent uncoolness can answer the question. Neff has fairly decent intelligence for being able to construct a moderately solid plan for cheating the insurance company. However, his evil intent caused him to become instantly uncool. Therefore, I would argue that the only way to be cool through having deductive skills and intelligence is to use these powers for good purposes.
