I believe in free will but I think it's possible it doesn't exist at a 100% level in practice as you allude to with genes, environment, history, brain chemistry, etc. If you imagined free will as Madden football awareness ratings, some will be close to 100 but many others will be a lot lower. So sane people aren't incapable of making the right choice but they are incapable of doing as reliably as others across multiple scenarios over time because there are a lot of other factors at play than being human and having free will.
