Classical free will even before determinsm had limits. Free will is only possible if you obtain information over a certain situation in time to be able to react. If a bullet is flying to you with close to light speed you will propably not be able to decide if you want to avoid it or not Now today our free will seem to be even more limited or non-existent as we provenly react to brain damage or drugs changing our personality. Based on what we already know about what limits our free will it might be possible that matter is simply a lot of information at a very high speed and that this is what limits our possibilities to react and make choices when we come in contact with damaging matter. And do not picture the travelling speed of the bullet as the problem. Imagine the bullet at rest and at the same time beeing high speed information (monism). Or as an analogy: the matter in the bullet is thinking quicker than you do at any moment, if you have an intelectual argument with it, you will loose do to your lower thinking speed. So in some sense brain science have discovered nothing new, namely as we all knew, external stimuli/information which we receive from outside can change our soul. If that would not be the sense we would have no attachment to this world, we could neither see it, smell it and so on. For example: Some information is coming into our soul slowly like a bad stench from the landfill and hence is slowly changing your soul to make you more angry (the process could as well be so slow that we can counteract and calm ourself) while some a brain active poison from the lanfill is doing it quicker, if you ingest it, and than your new anger mangamnet technic does not help anymore. Now we all experienced mood swings (become angry so much that others might temporarily not recognize us) to which we need time to adapt and reconstitute our personality. Is a brain damage that turns us into a psychopath simply something that our soul would need 100 000 years to adapt too without external help? Because than even the brain damaged person has free will and a charcater that would return- it would only take to long a reaction time in relation to the very quick thinking matter it got into an argument with.
