Well, I don't really know if god's unjust or not, I don't even know who or what he is, or even if he exists. I strongly doubt that he does, the available evidence doesn't seem to me to point that way, but I can't definitively state that he doesn't exist either, all I can say is that I don't believe he does. Which, I hasten to add in order to forestall the most common criticisms of that position (not that it's ever really worked) is not the same as believing that he doesn't. It seems clear to me that certainly some human concepts of god are pretty unjust, like the one that allows, perhaps even requires, believers to fly airplanes full of people into buildings full of people, or more generally the one that allows, perhaps even requires, believers to kill other people who believe differently than they do. History is full of examples of that kind of behaviour. "Thou shalt not kill" doesn't seem to carry much weight these days, and it doesn't look to me like it ever did. In practical terms that rule might be more accurately rendered as "Thou shalt not kill members of thine own family or tribe or belief community," anyone else is fair game.
There's really only one thing I'm sure of in this context: God, if he exists at all (which as I said, I strongly doubt) isn't remotely what anybody thinks he is.
