Arminians are fond of quoting Ezk 18:23 in opposition to Calvinism. But why do they think that passage is at odds with Calvinism?
In what sense do they think the Calvinist God takes “pleasure” in the fate of the damned? Predestination doesn’t mean God enjoys damning people for the sake of damning people. Even if God takes pleasure in justice, that doesn’t mean he takes pleasure in punishment for its own sake.
Moreover, predestination is not a synonym for pleasure. God can predestine something to take place, not because that “pleases” him, but because that’s a way of achieving his goal.
Why do I put gasoline in my car? So that I can use my car to go places I need to go or want to go. The fact that I choose to gas up my car, the fact that I intend that action, doesn’t mean I have to take “pleasure” in that choice or action. It’s not something that either has to please me or displease me. It’s just a necessary step to accomplish something else.
