I found this which helped me out -
Free Will, defined as the ability to have done otherwise, is not logically possible. All events must either be caused or uncaused, these are the only logical possibilities. In a universe where all events have prior causes, Free Will cannot exist as every outcome is completely determined by the given set of conditions; there is only one possible outcome. In a universe where some events do not have causes, Free Will still cannot exist as uncaused events cannot be willed into existence by a person, they would happen at random for no reason. These exhaust all possibilities, and therefore Free Will does not exist.
This, however, does not undermine our own causal agency, we causally determine our actions, and as such still have the ability to determine our futures to our liking. I would like to add that since most of the world assumes Free Will to exist, the truth that it does not exist would have significant implications in the real world. Holding others morally or ethically accountable for their actions, good or bad, is no longer reasonable given that they could not have done otherwise. A person's choice isn't ultimately up to them, despite how much they agree with it. This would change the way we view others, hold grudges, or even hate others at all. We would still need to lock dangerous criminals away for the safety of others, but to punish them or hate them for being morally depraved would be wrong, it IS wrong.
I think my confusion comes in with thinking free will and having a choice are one and the same as determinism and lack of having choice are once in the same. This is not so and is important. Especially when it comes to human belief systems in which people's choices are used as a license to intentionally cause harm to others or hate them.
