Short answer: No.

Long answer: Well, the film series so far has been influenced by the War on Terror. Then again, so was the Sam Raimi Spider-Man trilogy and the re-make of Battlestar Galactica. It's part of the Zeitgeist, just like Star Trek (original continuity) and the Superman films (starring Christopher Reeve) were influenced by the Cold War.

Batman doesn't kill. He does a lot of other nasty things, but when he uses the military cell phone sonar technology to monitor all of Gotham, Lucius Fox (who the viewers are to know as a "good guy") protests against it, because it violate people's privacy. So Batman only uses it to catch The Joker, and lets the system self-destruct after he has succeeded in doing so.

Furthermore, it's stressed that crime is to a great deal caused by Gotham's economic depression, and that the Wayne's combat that depression through charity and investments in infrastructure. The Waynes didn't sell (military) weapons, and it seems that Bruce Wayne stopped Wayne Enterprises from doing so after he became majority shareholder. It's also inferred subtly in Batman Begins and more direct in The Dark Knight that outsourcing is partially the cause of Gotham's (and USA's) woes and therefore *wrong*.

"Batman is only meaningful as an answer to a world which in its basics is chaotic and in the hands of the wrong people, where no justice can be found. I think it's very suitable to our perception of the world's condition today... Batman embodies the will to resist evil" -Frank Miller
