Yes, for starters you can familiarise yourself with the relevant arguments, here is a starting point:
Free Will vs Determinism - Orion Philosophy
Once you are familiar with those, you will begin to realise that simply insisting that ‘everyone chooses’ and there is no nuance involved is absurd.
However it seems quite evident that you have no interest in any kind of mature conversation. I suspect that you do not understand your own demand for proof and what that involves. What it involves, in reality, is you engaging in some mature behaviour. What I think you perhaps mean is proof along the lines of proving it’s raining outside by sticking your hand out of the window. If that is what you mean then you know as well as I do that your demand is silly and childish.

Free-will is only possible with God and unseen realms. The Quran says a day with God is a thousand years of our reckoning and things take a thousand years to ascend to God. Each day our deeds are presented to God and his Messenger and the security givers (the Imams), but it's not in a process we are familiar with.
Angels (a) and the unseen realm we are connected to make free-will possible. In this unseen realm, we have enemies too and can go wrong realms and wrong skies.
Once we associate with God, we are in a far place, and Angels (a) and Imam (a) are not responsible at that point if we reach guidance or not. However, if we enter the proper doors and fear God, the Imams (a) will guide us in the unseen journey.
The speed we race to God is a matter of will.
Ultimately, we are the creators of the realms in our souls. We choose what to tune into the good thoughts from God and Imam (a) or the evil thoughts from Satan and his minions.
The struggle to get out darkness to light is not easy. And it's not a matter of just a moment decision. Rather, each decision behind the scenes is an entire battle in the soul between light and darkness. Yet when we do evil, we feel guilt and when we do good, we feel good about it, so we are the ultimate decision makers. How those events take place, we don't know.
Man is a light, a secret on top of a secret. The Angels rank up the higher they help humans in ascension. Each day we witness is a entire thousand years of battle between Shayateen and Angels in the unseen realm.
