What is justice?

In previous blogs (here & here ) I've questioned whether or not 'justice' is an impossible 'idyll'; something we aspire to achieve, like the victims of Grenfell Tower, the Hillsborough disaster or the premature deaths at Gosport War Memorial hospital, but can never hope to fulfill. It seems the are always so many conflicting interests that one man's perceived 'justice' is another's travesty.
Can the Davies Hypothesis explain this conundrum? I believe it can by looking at the nature of good and evil. Normally we consider good and evil to be a one dimension continuum, with 'good' at one extreme and 'evil' at the other. however, the Davies Hypothesis demonstrates a better understanding if we consider good and evil as a three dimensional problem as explained in an earlier blog. http://www.kevilldavies.com/2017/11/good-evil.html

It seems to me that law and order are man made institutions whilst 'justice' is that spiritual concept, totally necessary for the good order of mankind but always unperceived like the Tao. Justice can then be thought of as 'imaginary' goodness in the diagram.
