I like what you said so much, to digress just a bit two thoughts: - I was thinking about the same lines few days ago watching coloring of Roman statues, and how they look lifelike, and then coloring of WW1 photos, and how it looks as business as usual, no fuss no drama, just another ordinary day - sky is blue birds are singing and humans are having war. - 2nd train of thoughts were some fiction "theory" how we humans were created by aliens as working force. And then somehow amusing thought was that if you have bionic robots or mechanic, but after they served their purpose (mining for instance) they need to dismantle themselves, all you need is to add a self-destruct feature, but feature must be part of the character so they will not suspect. So instead you as overload alien creating killer switch and risking they going after you, they will do it on their own ...

To go back to main subject, most of us are unaware are the things we do good or bad, we work to feed family or just to survive. Maybe some guy out there thinks he is working in strict chemical factory but in fact he is working for a drug lord or some dictator that is creating chemical weapon. For him not feeding his family is bad thing, and he does the job he is educated for.

Very much like biblical "Father, forgive them, for they do not know what they are doing."

Most of us do not, I am working on a banking software... maybe it will create misery putting in spiral debt some family that will become homeless...
