Free will: The capability to make a free choice.
Free choice: A choice that ultimately is not influenced by any outside entity and completely unpredictable, but also is completely rational from the perspective of the entity making the choice.
Note that a being with free will does not have to make every choice a free choice, but must only be capable of making a free choice.
Why Free Will Is Impossible
1. Every event is either caused by something or caused by nothing.
2. If an event is caused by something: it is not free because it is a reaction dependent on external cause.
3. If an event is caused by itself: events can’t be their own cause so this is impossible.
4. If an event is caused by nothing: it is unpredictable and therefore random; randomness is not free will.
Therefore, free will cannot exist.
