Whenever we make a choice, we are expressing some sort of a valuation. I agree that this comes before an analysis. This thread got started quite some time ago with the idea of including a moral axiom. This axiom was initially suggested as something on par with the existence and measurability of the physical world. I don't think moral axioms belong as part of a discipline.
Moral axioms are more appropriate to a religion.
With regards to the more recent stuff, I am just trying to say there is a difference between the choice of tools and the tool. A hammer is entirely inappropriate for scraping paint from a window, but pretty useful for driving a nail. If breaking the window is bad, then choosing the hammer is the wrong choice if one wants to scrape a window. The hammer itself is not wrong. It is just a tool.
