I agree. I explicitly said I’m only referring to which one is functionally more powerful.
I would point to history though, to show thousands of years where rape and child murder were considered just fine, in certain circumstances. You had to be conquering a city or something, but then it wasn’t too unusual to murder and sell the population into slavery.
Ethics, in its entirety, is also one of our creations. We all tacitly agree to something of a unified code of ethics that we follow to keep our societies running smoothly. This code, unless it was given by some divine structure, though, remains one of our constructions, through whatever governmental/organizational structure we exist in.
