Humans are fully capable of helping other humans. Most of us just choose not to. We are supposed to be self sufficient. Free will and such. But we cant let a year pass without another war starting.

It's not possible to *test* Cain because god knows the answer already. He know which response will be chosen. To suggest otherwise is to suggest that god is not omniscient.

Your argument is that there are certain possible choices that god knows about, but does not know which one Cain will choose. But re-read that last statement - "does not know." By not knowing something, your position is that god is not omniscient. 

You can't have free will and determinism at the same time. That is basic knowledge.

If God is omniscient then he knew every detail of what would happen on and around Earth before time as we know it started. The way things were, are and will be were completely determined by God, as he made the decision, again, before time started. I.e. had he decided to change some details of his creation we would have made completely different decisions throughout our lives. But he settled with our current situation.

LOL, that seems like a stretch. God does not want to intrude on Cain's free will of answering a question posed by God himself in the first place? Heavens no, this makes no sense to me. Perhaps if God was trying to get Cain to expose this information to a non-omniscient third party? Who knows?

I don't agree that free will and omniscience have to be contradictory. The foreknowledge of someone's actions do not make that action an act without free will. But then again, I also do not believe in the existence free will or omniscient beings, so whether they contract each other is a pure academic question for me.

I'm not saying there are certain possible choices God knows about, he knows of all possible choices and outcomes. It doesn't matter to him which Cain chooses as all are a potential reality.

I know my last statement and it's badly worded, I'll admit that. I was mainly trying to form a counter arguement to the idea that an omniscient being had to reason to question someone.

Who said it was G-D's job to do so in the first place? Typical flawed logic

Settled? Is this really the best option for this creation? Because it's a crap one. This is where my idea that Gods knows all possible outcomes of future events and the fact Free Will shapes this.

Okay, so now you're saying that all possible choices and outcomes are seen but god doesn't know which will be picked? That's still not knowing something, which negates omniscience.

Potential reality - the implication here is that there are probabilities associated to them, which implies uncertainty. Again, you keep admitting that god does not know things. 

You mean... like Cain himself? Get Cain to highlight to himself what he had done? An interesting thought indeed.

I'm not sure if God doesn't exist, if God is simply dense, or if he is Evil. None of those three pictures are very flattering.
