I could give you 5 Calvinist arguments off the top of my head.
1) When the universe was created, God had already ordained the plan of salvation, which means He already knew that billions would suffer in a wicked world. Yet He made the universe to be this way anyhow.
2) Romans 13 says God installs governments. So God installed the Roman emperors who martyred many Christians.
3) God forbids us to seek revenge, but He takes revenge, so clearly He has a different standard for Himself.
4) God hardened pharoahs heart to make things worse for the Hebrews.
5) Jesus was the author and finisher of a plan that patently required His violent death on a cross.
They can defend "God authoring evil" without even getting to pre-destination.
Now I'm not saying I agree with them. But they can make good arguments.
It would be nice if you would include scripture and context with each of your 5 statements, so we can understand where you are getting these things from?
