In which case, since the God of the Bible clearly behaves in a way that could only be considered unjust, one is forced* to reject the Bible, or at least reject the possibility that it is God's description of Himself.
[Edit: not forced, of course, just strongly encouraged, anyone is at liberty to believe what he wants. If one is bound to accept every biblical statement about God as true, then one is continually having to make excuses for Him, and finally opting out of any argument by concluding that as He is God He can do what He wants. If the God of the Bible is just, by definition, then justice has no useful meaning - or, at least, God's justice is not of any use as a model on which to base human justice.]
