I'd also like to point out that someone cannot go on a murder spree and still be in the right. Definitionally speaking murder is unjust killing. Now you might think objective morality exists because we tend to agree on the big things (unjustified killing is bad, stealing is wrong, etc) but if you start asking smaller questions you'll see there is rarely a clear consensus.
