That's definitely one world view, that people are responsible for how people use the things they create. Nothing wrong with it. I'd hold a different world view

That's definitely one world view, that people are responsible for how people use the things they create. Nothing wrong with it. I'd hold a different world view, in which individuals who have good intentions shouldn't be blamed for their work getting bastardized or leveraged in unethical ways. In this case, it seems totally reasonable that an engineer on this project would assume that their work would reward efficiency (which it does), and not be gamed to reward exploitation (which it apparently also does). Different strokes for different folks, I guess.
