So when God asked Cain “Where is Abel your brother?” His question was inappropriate or wrong because Cain is NOT his brother’s keeper and shouldn’t know at any given time where he is?
Were God to ask me where my brother is, I’d answer I suppose, “Lord, I believe he is up in (city, state), working on his house.”
Not, essentially, “How should I know? What do you mean by asking me that?” and correcting God’s question to me, as it were.
No, of course not! As I said above, it was a rhetorical question!
Being omniscient, God of course knew what had happened! He was NOT implying that Cain should know! He was, in essence, saying: "What have you got to say for yourself after murdering your brother?"
God never issued a commandment to Cain, saying "You are your brother's keeper, so I expect you to always know where he is."

That would be a nonsensical question on the part of God.
Being omniscient, he would never have to ask in anything but a rhetorical sense.
If God asked me a non-rhetorical question, I would reply: "That makes no sense to me! How could an omniscient being not already know?"
