If you are a random collection of atoms just like rock and zebras are... and you act according to the laws of nature there could be no free will, correct? If all of the molecules within you act according to those laws they are what generate your thoughts. How could you change them?
If you have no free will, how could you be accountable for "immoral" behavior? Who determines what is moral or immoral? What difference does it even make if you rearrange the molecules of some other being, whether human or not, if at some point the sun will explode and all life on earth ends anyway?
