when a child cries to you from the charred remains of their crib....is that justice? when a mother cries every night for her son to return home not in a box....is that justice? when the brave die young....is that justice? how is it fair that so many people die and suffer for the disagrements of so few? how do you justify fighting over something petty as money and sacraficing so many things of so much more value? justice......definition please
