Dimensio;I think that the point is that if God created absolutely everything that exists (except for Himself) and if God knows absolutely everything then God knew before He made his creation just how it would turn out, and He could have done things differently so that events would have worked out differently had He chosen. As such, He is responsible for everything that did happen, including evil, since none of it would have happened without His original act of creation, and because He is all-knowing and all-powerful, there's no room to argue that unforseen variables cropped up.
So according to you God is a sick sadistic monster Who is ultimately responsible for all the sin and rebellion against Him (which makes Him also a skitzo Who is at war with Himself) simply because He knew that by giving His creations free will that many would not chose to obey Him.
And God would have been much better off to create willess robots that could only do exactly as God programed them to...so He could spend eternity in the company of souless machines without the ability to choose anything at anytime...and no individual identity.
How awful of God to desire communion with free souls who were more than programmed machines...who were with Him out of their own free choice. Who desired to give love and be loved by creations who did so out of their own free choice.
Instead of denying free will or using it as a means to call God the creator of evil....can't you see the real implications of what an incredibly wonderful and benevolent God all this reveals Him to be?
