Free will doesn't exist but complicated enough animals, as agents with goals, decide on their actions. We happen have the most complicated decision-making skills. Sentience is nothing but your ability to self-simulate yourself including your feelings.
If you could exactly simulate the nervous system including the whole body, you could predict all the decisions. Such a system would be very complex and nonlinear so due to chaos it'll probably be nonperiodic (basically random) despite being deterministic. Indeterministic quantum effects (if they exist) are irrelevant because biology functions at a much larger scale, which is deterministic as far as we can tell. Even if it was truly random (i.e. even God couldn't tell), there's no reason to suggest (You) could control it based on your "will".
It's fine if people want to call it the "free will". When people are told they don't have one, they become more cruel because their decisions are affected by what they know. If the relative weight of "responsibility against society" decreases when decision-making, then they tend make worse decisions for the society.
