‘On the face of it’, it makes perfect sense.

But why bother?

If I’m on the ‘right’ side, why would I make it easier for the other guy?
If on the ‘wrong’ side, why not just switch sides? Why would I bother to straighten the tree? Against the wishes of those who have a lot to lose in the process?

From the other side of the looking glass, things are a lot simpler.

‘Fiat justitia, ruat caelum’ is a warning, not a behest.

‘Make sure that justice is served, unless you want the heavens to fall on your shoulders’ is what any open minded reader of history makes of this ancient adage…

The fact that we concentrate our attention on what justice means for each of us is a measure of our individualism.
Of our nearsightedness…

Our respective individualities, each and everyone of them, have grown into what they are now in a social context.
None of us can exist for long, let alone protect and develop their individuality, in solitude.

We need the others.
We, each and everyone of us, need to belong. To a community.

To a functional community!
To a community where each individual is cherished.
Where each individual can develop its potential.

Where each individual has the opportunity and the tools to develop their potential.
For his own good, in concert with the main interest of entire community.

Survival.
Things remaining as they should be.

Us toiling here, on the surface of the Earth.
The heavens perched safely up there.

Justice must be served if things are to remain as we, each and all of us, need them to be.
