I think this is a good way of putting it. But it draws to the main point: what is a 'just society' who decides it, what is just for you may not be for me? For example in the USA punishment for crime (including 'victimless' crimes like downloading a song or film) is a major part of the justice system. Whereas in Sweden the main reason behind the justice system is rehabilitation. Is one more just than the other? What if it isn't a victimless crime? Do you think everyone agrees with you? Does what is 'just' change over time, the idea of eye for an eye used to be pretty popular, whereas now, it is much less so. I think this is what OP was getting at, the idea of what a just society is changes (changes is fashion). But I think you really got to the crux of it!
