Well according to that he WOULD be a dick. Cept that you just made it up, and anyone can make up stories to make God sound like a dick. Thats not even an argument, what you imagine God to be doesn't me has to be that.
You see paroxsym, to me its the perception.
God didn't create me. I don't claim he did. If your going by the logic that God created humans, then whats the problem? Free will exist because i can do what i want. If he made an event that eventually led to me being born, its still free will.
IMO free will exist, the quote from Epicurus(hope i spelled that right) makes sense in the ideology of the time, when the perception of free will was much more blurred than now.
I simply don't see how free will is a hard topic to understand.
