This explains how Calvinism can say Gods justice is not the same as our view of justice. I.e., Gods actions can be what we would call an injustice.
>>You should read Robert Reilly’s book about Islam. It makes the similarities between the Calvinist God and the Muslim God plain as day.

It appears you both possibly misunderstand, and misrepresent Calvin, or at the least, a great many others.
It was written in the Mosaic Law that a son was not to be punished for the sins of his father, and the father not be punished for the sins of a son.
If a father sins, should we kill a child of his for it? The Lord has done so (or ordained it to be, which is much as doing so, as the one who directs or hires an assassin is as culpable for the killing, as the one who commits the act). Yet it was needful & just, when He did so with King David's illegitimate son.
He even sent His own Son to die, and for a brief time He separated Himself the Father, and removed His Holy Spirit too, taking that also from the Son, leaving him alone and despised to suffer for injustices and wrongs others had done, and would do.
No fair! That was not fair at all. The Son had done nothing to earn such darkness, that the sun itself was darkened. He didn't do anything wrong.
It wasn't for justice, save that there must be a penalty for sin.
And why was this miscarriage of justice, this crime not only allowed to be committed, but this time an actual legitimate heir to the royal line was ordained to be slain, but for love?
Where was "justice" when He stood in our place? Please, don't take this for granted, or you will entirely miss understanding those whom you here so frequently malign.
It must be written upon your heart. Who can make such a writing?
