Perfect randomness in infinity will generate infinite deterministic sequences. By the anthrophomorphic principle our lifes are located in the span of a string that is experienced as mostly deterministic, and we understand it as our bounded free will.

I would like to drive a nail in the coffin of “deterministic causality” by at least two mechanisms.

- In every scope there is a super scope which may influence in incalculable ways (however well their rules maybe understood.) Even in a model of the whole Universe, the base potential of cosmic background radiation (non-zero vacuum of void) is a non deterministic influence.

- ultimately radiological decay may not be predicted (a feedback mechanism of unpredictable external scopes)

There is more to consider yet these alone are enough for all physicists to agree that universal determinism is not actually possible.

Decay and the exogenous scope.

Everything in the universe fails eventually, only we may not know which part or when. Everything has an outside influence that cannot be predicted, even if that is how external decay will be involved.

These are NOT the basis of free will, merely an example of how determinism is a dead horse.

Free will is the “determination of resolve in the moment of now.” A different kind of determination than determinism. It is not that will cannot be coerced or manipulated or even anticipated (we are creatures of habit.) it is that the feedback loop in the mind is made of constructive and destructive interference and that may self reflect in unbound scalar ways.

What we think of as determinism is a blessing not a curse. Who wants the Earth to spontaneously turn to jelly? Or marshmallows to suddenly fall from the sky? We cannot function without mostly predictable outcomes.

There is no proven “deterministic causality”.

There is a free will that is easily proven.

I could give elaborate answer to your question, but I chose to give a short and primitive one.

You’ve made in the image of god and got a gift of free will. Live with it :)

Whether or not we have free will is not among our choices. It's complicated.

This is just a problem of self-reference. If you focus on determinism and act accordingly then you are stuck in a loop. You can sit on the ground and call whatever happens inevitable but that inevitability is a product of your behaviour.
