<p>Religion has nothing to do with it. The definitions of Murder and Slavery are dependent upon the norms of the society within which they occur. Without a consensus based upon accepted and codified morality there is only anarchy. You state that most, if not all, societies view life as worth protecting. I think that if you look around the World you will find that “most societies” do not view the definitions as you do. In many, if not most, societies around the world, what you or I might call murder occurs on a regular basis or is considered retribution for a previous wrong and monetary compensation is paid to the aggrieved family. In many, if not most, societies around the world slavery or servitude is considered the rightful place of those of lower class,status or ethnic origin. This does not include those segments of the world currently involved in war, famine, strife and revolution. You may call me cynical but as someone on another thread stated “it is what it is”</p>
