If we accept free will as the ability to make a different choice in the exact same scenarios, then I don't think free will exists. Every scenario has factors, factors which equal out to a choice. I don't see how one could make a different decision in the same exact scenario, with the same exact factors in place. Your personality has a certain disposition to scenarios and the factors within them, and it isn't logical that your personality would flip-flop if presented with the same set of options.
True free will is impossible as realitivity an many other theory might explain time is different in dufferent places and has a determinism of course it is very difficult to predict but determined all the same . That doesn't mean to do nothing it jut means that its predictable and should not be determined as a form of nihilism
free will doesn't exist.
Although there are certainly outside factors and internal factors such as brain chemistry and genetics that make one's decisions generally predictable, free will does play a role. Instinct can be overpowered and although it is uncommon, a few people going against their instincts would throw off any predetermined plan. The world is too random for determinism.
Free will, and chaos. They go hand in hand for a reason. The unpredictability of an unknown suddenly coming into an equation. Even if after the event occurred, and you came up with how the unknown came to be what if the person investigating found it was absolutely random? Then what? Of course they might just label insane. What if insanity is freewill?
