Justice signifies the principle that although things sometimes seem askew the Universe is ultimately fair. We may not see or understand why things happen, but most of us sense there is in fact a reason and that balance exists even when we cannot see it.
Justice denotes fairness regardless of who you are. At its purest the forces embodied by Justice give us the power to see without bias, and the courage to be accountable for our actions. These powers also test our faith at times. These powers also give us the tools and strength to fight injustice in our everyday life. All we have to do is use them.
