Free will is impossible
We are made of molecules and their behavior is dictated by laws of chemistry and physics. Even if you believe in a soul, the soul is trapped in a body made of molecules, so there is nothing it can do.
(*neuroscience completely debunks souls, why people with head injuries have predictable personality changes? Many become cruel and heartless, some become docile and fearful, And it all depends on which part of the brain was damaged, did their soul change after the flowerpot landed on their head?)
let's assume we are each assigned with a soul in which case you still have no control over the properties of that soul you received and how that affects your physical body. so you're just kicking the can down the road.
*****somebody mentioned that study of quantum mechaniques shows that physics at quantum level is not deterministic. well it's still random therefore outside of our control.
