"Justice is rectifying the wrongs that people have suffered, and if possible, preventing those wrongs to begin with."
- How do you 'rectify' things for the victim of a murder?
- What is a 'wrong'?
- Does justice occur before an Act? Would a pre-emptive attack then be justified under 'preventing those wrongs to begin with'?
I don't think that true justice can be codified - although consistent justice can be - and consistency is one of the principles of justice (hence why laws a codified)
Eluding codification, it probably also eludes easy definition.
In the end :
- civilly, it's an unbiased balance between interests (individual v individual v social v environmental).
- Criminally, it's a fitting punishment (where the crime is meant to be balanced by the punishment), and a tool for a level of conformity and peace.
I don't see justice as 'fixing the problem' (it's after all already occurred, and many crimes aren't fixable by a justice system), nor as revenge (which isn't unbiased).
