whether you believe in a god or some version of a god...or no god...
does justice exist?
if justice is a man-made construct, fashioned over time, to create a social order, whereby we can live together in packs, with reasonable sanity, then...morality is merely in the eye of the beholder...if a man can do as he pleases while avoiding the consequences of that behaviour and escape any form of punishment in life and in death, then there is no ' right and wrong '...no justice...murder or any other crime is merely socially unacceptable behaviour and has no moral statement...
as a man-made social construct morality can change at the will of the social order...therefore it has no existence as something other than whatever we decide it be...if we decided that it was acceptable to kill then we would be right in the eyes of the social order...
and this at face value appears to be true...
as different societies have different morality, and time changes a social morality from generations...
however..if morality exists as a thing, apart from man...then we are beholden to it, and cannot escape it, in life or death. If we id not create it, and do not control it, then it is unavoidable...and that would stand to reason that a man who avoids punishment in life cannot escape it in death.
Either morality is a man-made construct, that has no existence apart from whatever man decides it to be...or...it exists apart from man as a thing onto itself that we cannot avoid.
If the former then justice cannot exist, and people like Hitler or Adi Amin, did nothing morally wrong, because morality is whatever a society dictates it to be...
so a rational man must, by necessity, come to the conclusion that this cannot be the case and that morality must exist as a thing onto itself...
so whether there is a god or not...sanity dictates that there must be an order...and that order includes a moral code that demands justice that is beyond our control.
IMO
