Most of the time, we don't care actually. Only in philosophical discussions similar to this one, we talk about free will. To me, it seems that it's really an unnecessary assumption. In my everyday life I just don't care whether someone has free will or not. It's more about a meaningful interaction or to get something accomplished together. I guess we need to separate simulations about the real world happening in our brains from the actual reality. Actual reality is based on quantum mechanics. Of course our brains developed as an organ that supports survival of the organism. So there's not really a reason to reflect an accurate picture of physical reality.
