The sandwich analogy doesn't work, because there are not enough variables to cause significant chaos to the point of where a will can be proven. Will implies thinking and decision making in a chaotic environment so as to assume intelligence, but being only able to choose three choices and starting out with 2 demonstrates no more intelligence then random chance.
Intelligent choice is part of free will, because otherwise it is only instinctual choice. But intelligence by nature allows malevolence, because it allows you to create choices where there were none.
Also, a paradox doesn't disprove the existence of a god - if anything, any omnipotent being of any sort would be paradoxical by nature, as omnipotence can only exist in a paradoxical state. If you're wondering how that could be possible, light is a good example - it is both a wave and a particle, and yet it exists. Being a paradox doesn't exclude the possibility of something existing.
Lastly, omnipotence doesn't exclude desire. For example, if you suddenly gained omnipotent abilities, would you actively use them all? Would you change certain things? Would you change yourself? Would you create something?
Why?
The same questions could be true for any omnipotent being.
All that said, this simplified chart is missing some options, but then condensing philosophy into a simplified chart is already quite reductivist anyhow.
