As an analogy - what's the difference? What if the error was in the machine's control system logic? Should, or should not, the production tool (and software) be held accountable for what may have been ill advised use of the machine? (Reaching inside to seat the metal sheet sounds like a dodgy move. Bad design? Broken machine? Stupid operator?) When tragedy strikes, we, as moral animals, want to assign blame. Seek justice. Maybe even retribution. Unfortunately, our justice-seeking missiles are rarely a precision instrument, and the ultimate cause of the accident may have been well away from the floor of the accident itself. It might have been the software engineer. Who knows. But the question (as a hypothetical) remains -- if it WAS the software engineer for the control system of the widget-stamping thingie used at LG's factory in Mexico, should that engineer be held accountable?
