When your run-of-the-mill soldier (IE not Hitler) gets charged with murder for killing someone during a war, let me know. Until then, not ALL killing is murder.
Joe, if people actually CARED what the Bible said, there wouldn't be wars. Every doctrine of faith has a set of primary rules, and "no killing" is usually in the Top 5.
And by "usually" I mean "always".
Also, by "Top 5" I mean "#2" if it's a monotheistic system (see: Christianity, Islam, Judaism) or "#1" if it's polytheistic.
