What is justice

What is justice. Can there ever be true justice. Lets say you lie to your parent's should the punishment be any less than that of murder. You would most likely say yes that murder is a greater sin than lying. But in God's eye they are sin and sin is equally punishable. The guilty verdict for these crimes against God is death. This would have happened if Jesus had not been crucified. Therefore god being the ultimate justice took us off of death row and put us on parole. Giving us a chance to redemption.
