Justice

"Justice", at its base, means "to be just, fair". More commonly however, the meaning of justice is to punish a criminal that has done something wrong in a suitable manner that fits their crime.

Justice, in this sense, can be served by a criminal in many ways from receiving a fine, serving time in prison or execution, to name a few. The classic view of how a criminal should 'serve justice' is thought of as "an eye for an eye", which means if they have done something wrong, they deserve a punishment as great as the crime they committed. If a killer murders someone, then according to this term, it means they themselves should face death as a suitable form of justice.

One Piece Justice
The thing called 'justice' changes its shape... Depending on where you stand.

-Kuzan on Justice to Saul.

Justice has been used many many times in the series; the CP9 use this term against Iceburg, the Marines use this term to catch pirates and criminals. Justice is used in an archetypal pattern often at times (e.g. someone would talk about doing things "In the name of justice" or "ridding the world from evil"). A common theme is that corrupt members of Marines and CP9 often use Justice as justification for their actions, putting every inhumane thing they've done as a necessary evil to preserve peace to the world, this has often led people (most of them pirates) to react with disgust at their behaviour.

Absolute Justice
...Absolute Justice... Sometimes drives a man insane.

-Kuzan on Justice; in regard to Akainu's actions at Ohara

Absolute Justice (絶対的正義, Zettai-Teki Seigi) is the belief that many marines hold.

What is Absolute Justice?
Marines following the rule of Absolute Justice will be noted to display some or all of the following views:


 * 1) Anyone connected to criminals, no matter who they are, can be arrested even if they have not done anything.   Even if the criminal is family, they must be captured or killed. Particularly with dangerous criminals, women carrying their children or the children of the criminal, can be arrested or killed to prevent the possibilities of the child continuing their parents' actions.
 * 2) All individuals noted to have done illegal activities or criminal acts will be reported to Marine HQ and issued bounties, based the known information on their threat level. Regardless of the circumstances.
 * 3) Raising the Jolly Roger, mentioning, or being associated with pirates can be taken as a criminal offense.
 * 4) Any country caught harboring pirates can have further actions taken against them.
 * 5) Destroying an island to eliminate a problem is an option.
 * 6) Innocent lives can be taken to prevent the possibility of a criminal escaping.
 * 7) Any Marine who hesitates to take action against a criminal as ordered can face punishment.
 * 8) Slavery is ignored as it is seen as an effective means to handle criminals.

Moral Justice
Moral Justice: Much like "human justice".

What is Moral Justice?
Marines following the rule of Moral Justice will be noted to display many or all of the following views:


 * 1) Giving someone a warning without charges being pressed against them.
 * 2) Refusing to receive promotions for criminals who have stopped other criminals.
 * 3) Refusing to capture criminals, sparing criminals, or ordering other Marines not to arrest criminals.
 * 4) Allowing a criminal to join the Marines so long as they forget their past.
 * 5) Refusing to obey orders on moral grounds.
 * 6) Questions the orders of a superior officer.
 * 7) Dismissing Marines or other member of the law who are too cruel in their ways.

The Opinion of the word "Justice"
Pirates are evil!!? Marines are righteous!!? These terms have always changed throughout the course of history...!! Kids who have never seen peace and kids who have never known war have different values!!! Those who stand at the top determine whats right and wrong!!! This very place is neutral ground!!! Justice will preveil you say!? But of course it will!!! Whoever wins this war becomes justice!!!

-Doflamingo on Justice

While currently, only two types of justice are shown in the series Marines may choose to display signs of either form of justice based on their own interpretations or opinions. Some example of different opinion-based ideas on justice include Aokiji who declared he served a "Lazy Justice", Rob Lucci who claimed to serve a "Dark Justice" and Smoker who told Tashigi to create her own "personal justice".

In the CP9 Mini series, Rob Lucci was seen to have done an "Excessive Justice" to the Candy Pirates. The extreme nature of his attack against them horrified the citizens that witnessed his strike.

The Doctrine of "Absolute Justice"
The Marines follow a strict motto of "Absolute Justice" (絶対正義 Zettai Seigi), when it comes to prosecuting those who violate the government's laws. It is a central tenet of Marine doctrine, to the point where the word "Justice" (正義 Seigi) is emblazoned on the uniform coats of all commissioned officers. Pirates have been especially singled out by the Marines as a major threat to order. They are considered criminals regardless of whether they have committed any crimes other than raising the Jolly Roger. Civilians, too, are targeted by the prohibition against piracy: persons known to have associated with pirates are barred from entering the Marines (there are notable exceptions), and providing aid or comfort to pirates is a serious crime, especially if they are well-known bounty heads.

It's not known why the World Government supports absolute justice as much as it does nor where the ideals centered around it originate from, however Vice-Admiral Onigumo best described it as willing to sacrifice anything to defeat what is defined as "evil", though it does ensure that the majority of the world is held under the World Governments thumb effectively giving them absolute control of the world. However, this thought of Absolute Justice is seen to be clearly ignored if a World Noble is committing the acts.

"Absolute Justice" vs. "Moral Justice"
One of the ongoing themes of One Piece is the misapplication of the principle of "justice" by the Marines. While the Marines wish to maintain law and order by apprehending criminals, the techniques that it (or at least some of its members) use can often be no better (or in some cases even worse) than the pirates they seek to wipe out, trampling the rights or needs of civilians in order to pursue its own ends. They are also shown to willingly sacrifice the lives of other Marines in attempts to pursue absolute justice, often sacrificing large numbers for the sake of one or two criminals. Thus, proving that, judging from their morally-questionable actions, the Marines are just as bad as, if not worse than, the enemies they fight. Even going as far as to kill a boat load of innocent civilians, archeologist, and even babies and mothers, clearly completely innocent of any crime, just because they might have been the child of a famous pirate; out of irony despite this failing to actually kill the wife/lover and child of Roger.

Trivia

 * Though extreme, the act of punnishes those who have anything to do with piracey was also common in the real world, hence why many pirates used nicknames to protect those around them.
