Regarding Skinner's free will, he said that the only reason this free will happens is because people cannot control their behavior, but what I see is that they cannot control their behavior because they get satisfaction in every action they take. Skinner also has a theory that says "Behavior is learned, not chosen"; this is real. We can commit to every behavior, but it's our choice whether to do it or not, but since Skinner believes that people's behavior comes from the environment, here comes what he says about free will being an illusion: there is really no free will because we are based on whether the actions we take are good for others or not. Even if we want to do the action, if the result is not going to be good for everyone, we still can't do it.
