Philosopher of religion Alexander Pruss constructs an imaginary dialogue at Prosblogion between "Ari" and "Cal" on the question whether, given the truth of Calvinism, God can still be just. Here's the opening exchange:
Ari: Consider this horrific theology: God forces Sally to sin, in a way that takes away her responsibility, and then he intentionally causes eternal torment to her.
Cal: I thought you were smarter than that. That isn't Calvinist theology! Calvinism holds that God intentionally causes people to sin in a way that retains their responsibility, and then punishes some of them.
Ari: I didn't say it was a Calvinist theology. You agree that this is a horrific theology, I take it?
Cal: Yes, of course.
Ari: Why?
Cal: Because God is punishing an innocent.
Ari: I said nothing about punishment. I said God intentionally caused eternal torment. I didn't say that the torment was a punishment.
Cal: How does that make it not be horrific?
Ari: I agree it's horrific. I just want to get clear on why. It's horrific because eternal torment is intentionally imposed on an innocent, right?
Read the rest at the link, but Calvinists are forewarned that they will not like the way it goes. Be sure to check the comments as well.
