Is there ultimate justice?

Just looking at the children playing outside where i live, they are totally obliviuos to their Iraqi counertparts.Yet these children will be forming an ethical picture of the world that is based on fiction.

Children playing in a large shopping mall,in the mall is a farm display of goats, baby lambs etc, the mothers are also joining in with cuddling the lambs yet no one notices that the farm display is next to the bucthers where all the dead carcass's are on display.

Why should anyone species concept of justice have any precedence in the universe?
