For my part, I refuse to work on tech that is a 'single-bladed sword'; I'll work on something that has broad application, but not something with only 'immoral' application.

The crux is where to draw the line of morality. I think that's a reasonable discussion and worth deeply conversing about; morality is both an individual and community affecting thing. Both your self and your community need to consider it.

Rightly divide the words spoken and think about whatsoever is true, just, and commendable...
