God chose not to know.

Great name btw lol
I agree mostly with this. God knows all things. The Bible describes that we are made in his image, we are God's "thoughts".
Imagine a God existing only in himself with absolute nothingness aside from himself. Why create something like himself with no free will? He could, but if we also believe God is love, then no free will would equal no love. Love has to be expressed. And it can only be expressed thru free will.
So God knew of the probability of sin, but chose to let love express itself out. Or not.
