What is justice?

[Manjushri]

I've been thinking about this phenomena. It just seems so delusional, to think in terms of satisfying justice. I can't pinpoint the ego mechanism of justice. Is it desire, aversion, attachment? I'm talking about both the broad term and the narrow one. (narrow - why is it *just* for a criminal to be pursued and persecuted and get his sentence) 

What is justice? What is the root of a desire for justice? Is it innate? 

[Leo Gura]

Treating others with the same respect you would treat your self.

Selfless love.

[Chakra Lion]

Justice is making a ruling that seems Fair.

What is just to Kill or Create, Communicate or Consume.

A Good Judge wants Balance, replacing something negative with positive.

The Root of Justice could be Judgement, Contemplation, Reasoning, Order.
