We think we choose what we like, what we think, how we act, what we say, what we do. WHAT IF we have no choice at all?

WHAT IF whom you are is the very same person you were PROGRAMMED to be it inception/conception  via DNA over which you have zero control and you have no choice at all? You just think you do? Would you rather know or not know if it were true? Does knowing your responses thoughts everythings are robotic reactions too hard to take or comforting because if you can't choose how can you be responsible/accountable/blamable for anything?
