Rabbi Abraham Joshua Heschel wrote in 1962 that many people favor the idea of justice in the abstract, but praise of the ideal is not nearly enough.
“That justice is a good thing, a fine goal, even a supreme ideal, is commonly accepted. What is lacking is a sense of the monstrosity of injustice…Justice..is not an abstraction, a value. Justice exists in relation to a person, and is something done by a person. An act of injustice is condemned, not because the law is broken, but because a person has been hurt” (my emphasis) (The Prophets, pages 260 and 276 in Harper Perennial Classics edition, 2001).
