well, that opens to a larger question. I don't have all that much confidence in Homo Sapiens as a species. And curiously enough, old style Protestantism sort of agreed with that take in seeing man as a fallen creature and thus that it was an obligation of culture to erect as much curbing as possible around the straight and narrow path so that fewer people with prediction to fall off than might. The new prosperity gospel version of US Christianity sort of tosses that out the window with a new "I'm saved, I'm saintly, I can do anything I want" view of mankind. But that's another story.
Not sure why you are down on brain science, its objective facts stand up to scrutiny a lot better than religious opinion.
Of course the fun part is response can be conditioned as well as the response driving subsequent behavior!
