Once again, in order to use the Bible as an argument, you would have to have faith in it. Faith is an emotion. I totally agree in all of your statement except for the last sentence.
My only concern with that statement is that if you FEEL so strongly towards God to where you feel that murder is immoral, then you still bring your emotions into play with that debate.
My main question is, What do you consider GOD? Are we talking about "religions" GOD(S), or just a supreme being/creator?
