The term Justice, the very mention of the word is now so evocative stirring in some, rage filled emotions fueled by a strong sense of revenge. It evokes basic emotions supposedly suppressed or harboured in the Freudian subconscious that many would describe as "coming out of nowhere", very intense feelings that may even overwhelm a person.
I believe that justice is a basic need; but not everyone can get it at will. yet almost on a daily basis in an our interactive society all individual are done at least one injustice. Some can submissively overcome an injustice done to them but this is a temporary treatment and it it is accumulative. So naturally when it crosses the threshold of tolerance an attempt is made to cure ALL THE ACCUMULATED INJUSTICE.
By this description justice is not an appetite-driven sensation but more of a basic reactionary mind-set with a self validation of "one is nothing less than human". It is this basic component of justice that makes me say that it is the enemy of peace in the world. I can elaborate further by saying that there is no society where an injustice is not being felt, whereas the pursuit of justice in some cases is overextended resulting, in many cases, on an injustice on another (it over-spills so to speak).
