Do you believe people generally have free will? It is generally defined as the ability to choose how to act. I don't think it is wrong to say that most, if not all, societies are based on the assumption that free will exists, hence, we hold people accountable for the choices they make. Determinism, on the other hand, poses a threat for a lot of things we take for granted.
Also, please no Wikipedia links whenever you want to refer someone to a concept. If you want to use a concept as part of your argument then you should be able to explain what it is yourself and show understanding of it. Merely claiming knowledge of it and providing a link to an article on it is not a good way of arguing (unless there is disagreement on the definition of the concept).
