What makes society just?

In a just society people are morally good. For a just society it really depends on our own ideas of what just means. I believe it is helping others and acting responsible. This is my idea but many others would disagree. We all generate our ideas of the perfect or just society. It is personal preference. Society is just as long as we make it what we want. That may sound confusing but I mean we use our ideas of what a just society could be and we spread it. We tell as many people as possible. We then become a leader in the movement of reshaping society. Then a just society in your own terms. So society is just when you make it just.
