I think the answer is obvious. God grants His creatures everything but perfect knowledge. It is our responsibility to seek this knowledge from God. It's this knowldege that Eve and Adam lacked. It is also the knowledge that Satan lacked. When man (and Satan) failed to seek God's advise, they fell. You can hardly blame God for people not coming to Him with their problems.
There is only one thing that man relies upon, and that is God. When man strays from that path, he sins.
I can pose thousands of questions like this.
Any other questions? Please just don't ask me about the Trinity or eschatology.
Good one, HarleyD! Also -

but fear thou God.
