Interesting that many people here think that software engineers, as a population sample, have a 'moral disposition' spread fundamentally different from any other profession. I think we all know that is not the case. Some would even go as far to say that tend to be more morally ambiguous relative to everyone else, purely as a function of the type of personality the profession attracts (although it might just be a matter of perspective or priority). There's a more than enough engineers in the long tail of people financially desperate, intellectually interested or simply pro-SOPA to build it.

And then let's not forget the miserably misguided geniuses who created a airborne H1N5 virus in the name of research. Evil comes in many forms.
