"Knowing what is good and bad has nothing to do with Christianity"

OK then Gnome I will ask you the same question I asked Jim - who was it taught you what was "right" and what was "wrong"? What was good and what was "evil" Unless of course you are trying to tell us that you popped out of the womb inherently aware of those concepts.

You, like everyone else would have been taught by your parents, primarily your Mother, then by the Church in Sunday School and then at School. IIRC your parents, or at least one of them is/was Polish who came to the UK to fight the Nazis - if so then the chances are that he would have been brought up himself and taught the values and concepts we are talking about within the strict teachings of the Roman Catholic Church which was and still is very strong in Poland - it was after all one of the institutions, along with the "Solidarity" Movement that helped to bring down communist domination of the country in the 1980s.

And as you brought it up, over 2000 and more years ago Gnome, in these islands, the guy who wielded the club, axe, or sword the best dictated what was right and what was wrong, what was acceptable and what was not and it changed as those men died and were succeeded by others. Then as time passed and invasion followed invasion those invading brought in their own "rules" and imposed them on the indigenous population. The first time there was ever any thread of common understanding on what was "good" and what was "evil" came about with the spread of Christianity within the Roman Empire and beyond it.
