Nobody's decisions are solely their own. I do not mean from a philosophical or theological way, but naturalistic. Culture, subcultures, and other societal structures are a large impact on what people think about many things. Inequality is also a huge factor in predicting one's actions. As the Strain Theory puts it "when the myth of equality is met with the reality of inequality, deviance may occur." Many things contribute to deviance, as well as other actions, many of them social. Biological forces also greatly influence one's actions. I am not suggesting having a larger forehead means someone will definitely be a criminal. If you want to see the effects of biology on one's reasoning, simply speak with a drug, or someone under the influence of various drugs. You may say "but they still choose" but if one's choices are influenced so greatly, is it is not truly "free" will, but limited will. If a number of armed men stormed into your room right now, and handed you an apple and told you "if you do not eat the apple, we will kill you" is your choice to eat the apple a free choice? Or as Johnathan Edwards put it "You can do as you please, but you cannot please as you please." If one's biology influences what they desire so greatly that it is the only thing on their mind, was it actually free will?
