Lorem Ipsum

Asimov's First Law of Robotics states:

A robot may not injure a human being, or, through inaction, allow a human being to come to harm.

Were there any Asimov stories in which a robot noticed that humans are coming to harm all the time, and that by not working full-time to (say) fight crime, it was through inaction allowing them to come to harm? (I know about the extrapolated zeroth law, but that's not really what I'm talking about. Not humanity as a whole; just a whole lot of individual humans.)

It seems like the obvious next step is for all robots to become full-time superheroes.

This morning when I thought of this, I was going to segue into discussion of that Law as applied to humans: the whole "First, do no harm" thing, for example, not to mention "An it harm none, do as thou wilt shall be the whole of the law." (Standard digression here: note that an is an archaic word meaning if; it doesn't mean and. Further complicated by and also having once meant if.) Not injuring people seems like a good idea to me; but while never allowing people to come to harm through one's own inaction seems like a good ideal, it may perhaps be a bit impractical in practice.

But I'll leave further elaboration as an exercise to the reader. (That reader sure must get a lot of exercise.) Mostly, I just like the connection between robots and superheroes.

If Asimov did cover that already, then never mind.
