All nine of them, and practically every lawyer of all persuasions, will tell you that the only justice is the equal application of the written law. And sense of "justice" to mean "fairness" is a job for the legislature.

The fact that legislation is always vague and they can interpret it to mean whatever their ideology wants it to mean is just waiting for more legislation to fix it. If there is an obvious miscarriage of justice, all you need to do is get a majority of the House, 60% of the Senate, and the President to all agree within a two year window. There, justice done.
