Your first sentence is your first mistake. He doesn't predestined us, he knows what were going to do. Again this harkened to my analogy. I knew you was going to respond, I didn't forced you to respond.
You can't say that god created people and knows what they will do while simultaneously saying predestination doesn't exist. You described predestination to me and said "yeah, but it's not predestination, though." If an outcome is known, then it is predefined. If someone already knows what you're going to do then you can't choose to do something else.
An all-powerful, all-knowing god creating humanity is no different than a human creating a robot. The robot has a predefined set of activities it will perform the moment it comes into being and it is not possible for it to perform those activities outside its given parameters. It doesn't matter if the robot has just enough self-awareness to believe it is doing those given tasks of its own volition. Does a Roomba (a vaccuum robot), for example, choose to stop at walls? Does it think "I don't want to run into this!" and stop? Could it run into a wall even if it desired to do so? The illusion of free will exists if we don't know the Roomba is a robot. If I gave it to someone who is exceptionally gullible and told them it has self-awareness, they might think it really does and makes its own decisions. However, given the knowledge that it has a creator who knew exactly what it would do, we know the Roomba really had no free will at all.
