Irrespective of whether or not there is a God, how do YOU justify prohibitions against murder?
If I were to play the Devil's Advocate, I'd say your reasons are BS.
Normative ethics identifies such prohibitions as societal pacts that have obvious benefits for all members.
Yes, And those social pacts are built around the concept of reciprocity and certain moral axes, the most common being the Harm/Care axis, and Fairness/Cheating axis.
You didn't use logic or reason to get into this opinion, I cannot use logic or reason to get you out of it.
You cannot over estimate the unimportance of nearly everything. John Maxwell
