I think your analogy is incorrect with regards to doctors (since we're talking about action, not inaction). A clearer one might be: is the doctor who saves the life of a murderer, rapist, etc a wrong for doing so. We say "no she isn't" because she's absolved of responsibility for that decision by her medical oath...if she wants to remain doctoring, she HAS to offer her services without regard to the who the person is. In the case of the programmer, there's no such (legal) obligation.
