There's no objective morality, but that's not the real point. It's not the point that morality has to somehow be a stone, or something that can be touched. 

The options that are available to choose are determined to a point, and this is the objective aspect of morality, ethics, goodness, fairness, justice. 

The subjective aspect can still remain subjective, but that doesn't mean goodness is relative.....at all. The measure of a man is a man.
