Direct Answer
Devs does not definitively prove free will, but Lily's refusal to shoot Forest is the strongest challenge to strict determinism.

Why It Matters
A many-worlds reading can explain the same event without proving traditional free will.

More Questions About Free Will
Lily throws away the gun because she has seen Devs predict that she will shoot Forest and refuses to let that image determine her action.
Devs strongly explores determinism but does not prove it, because the final prediction breaks from what the machine showed.
Devs can forecast future events with frightening accuracy, but the finale shows its prediction is not simple unbreakable destiny.
The final prediction fails because Lily sees the forecast and refuses to perform it, exposing a limit in Forest's belief that the projection is the only future.
Many-worlds can explain the ending by treating the failed prediction and the simulation as branch-like outcomes rather than one fixed timeline.
The ending means Forest's deterministic certainty fails, but Devs remains powerful enough to create a morally serious simulated afterlife.
