Option 3 - your logical leap was invalid, and it is perfectly possible to be human and believe in truth and love and morality and all the rest of it, all within a deterministic physical system.

Choice is deterministic, but that doesn't make it less real - on the contrary, it gives your choices meaning! They have causes, reasons, justifications! It would hardly be preferable if your "choice" were the outcome of a fair dice roll, would it? What kind of choice would that be?

I think the problem arises from a confusion of of abstraction levels. At the level of atoms and chemical reactions, you are completely deterministic and "choice" isn't a meaningful concept. 10 stories up, at the level of thoughts and ideas, it is. This is no different than how "pressure" is a meaningful concept for a tank of air, but not a single air molecule.
