That's an intellectually dishonest question and you know it, you ought to be ashamed of yourself.

How? It's a legitimate extension of the previous thought. If it is viewed as evil to develop instruments that would kill people, is it also evil to use those instruments to kill people? Likewise, if no one developed instruments to kill people, the military would be an ineffective organization at the task that it's responsible for, and thus would the organization also be considered evil?
