It could also be read as a dramatic exaggeration of the parent's claim that one class of crime was better than another and that we should be willing to commit crimes of civil disobedience based on pragmatism and not be tethered by morality or legality. I tried to point out the absurdity of that claim by extending it as far as I could, by arguing that we should murder government employees so long as it "might" make the world a better place.

I thought it was clear by copying the words of the parent in my post what I was doing.
