I think the emotional reaction people usually have to “determinism” is nihilism: the feeling that what they decide doesn’t matter because everything is predetermined anyway. But to me this isn’t logical. “Determinism” doesn’t mean that choices don’t have consequences just that choices are predictable. Are my decisions predictable? Probably 
Are they important? Definitely.
I like to use the analogy of a computer controlling a light water reactor. If it decides to raise the control rods too long, that decision will have consequences even though you wouldn’t say that the computer has free will.
And if we pull in the Halting Problem we see that determinism isn’t so bad as it seems at first blush: even if you’re just a computer program, the only way to perfectly predict you is to run you. As Dr Seuss said,
Today you are You,
that is truer than true.
There is no one alive
who is Youer than You
In other words: you are the program that gets to dictate what you will decide. And if that’s not free will, I don’t know what is!
