My objection is soley directed towards mainstream Christian/Muslim theology. If your view differs from theirs, then my argument was not intended for you.
I hold myself fully responsible for everything I do within the limits of my capabilities. However, despite my decisions, God knew what I would choose, and he created me anyways.
As to good and evil, I have no reason to think that they are anything more than human inventions. But even so, we can say that God may be evil according to our created standards.
