The escape velocity is dependent on the mass of the two objects close to each other. For one object being much more massive, like a moon and a baseball, the mass of the smaller object can be ignored. There is more roundoff error and truncation error in the math.

Yes. And I do feel that way. But I also have rules I live by. One of the David Tenent Doctor Who episodes (I think a Good Man Goes to War?) mentioned who needs those rules, and why.
And no, I'm not Dexter.

If through inaction, 5 humans die instead of one, that violates the 1st law.

I read Asimov so long ago I have forgotten most of it. But what I remember the most is the three laws, and then the zeroith law, as R Daniel dedicates his existence to the survival of mankind. I think that philosophy changed me, and directed me. That I don't matter, other individuals don't matter, not if we threaten the survival of humanity, which is paramount... THAT matters.

Not exactly. What I am saying is that the mass of the ball is mostly irrelevant, and the only relevant mass for calculations of escape velocity are massive bodies very close to the ball. In this case, just the moon. The escape velocity is determined by the moon mass, not the position of other masses.
