Umm, well my parents traits became my own and my community kinda determines the rest. I make my choices based on those realities.
Well, if you had a pre-existing "soul" or whatever, then you could [in theory] optionally have assumed the identity of a different body or personality. Since the authentic "you" would really be that immaterial or abstract entity.
But as nothing more than a brain/body with a specific life history, you would instead cease to exist if replaced by a different body (person) or even via a clone of the current body but one possessing a different psychological configuration and past. There are no "I could have decided differently" or "I could have been someone else" options when you lack a prior-in-rank identity (soul, etc).
The latter situation is what a compatibilism view of free will rests in, that's independent of how particular adherents may contingently muck it up with their own potentially skewered and misconceived formulations. IOW, an imaginary "soul" or supernatural component is no benchmark or basis for justifying the autonomy of a natural organism upon. That would be akin to science perversely borrowing dogma from religion rather than practicing methodological naturalism.
In contrast, the whole point of an incompatibilism view of free will is to define FW so that either it or determinism (in the context of libertarianism) is dead before it leaves the starting gate. Incompatibilism desires the "soul" POV as the criterion, similarly regardless of whether its individual advocates have the capacity to lucidly apprehend that as being what they're working from or not.[1]
But hard incompatibilists are correct that indeterminism or "randomness" is not what could supply autonomy, since that would just be a non-governed, external "intruder" interfering with the otherwise regulated processes of the brain/body. Volition or "guided will" entails organization, not a lack of systemic characteristics. That hard incompatibilism conclusion arguably has no reliance on assuming a prior-in-rank identity or mystical "soul" stuff -- it's a realization that should fall out of compatibilism as much as it does incompatibilism.

[1] The brain/body coming into being with a confining template / configuration that makes it susceptible to predictability, and subsisting through a chain of different states (time, causes-effects) in the course of its self-management -- is the inherent way it exists. Only an overall thought orientation taking its lead and evaluating standards from supernatural religious beliefs would penalize the organism for its own existential attributes, via misplaced features and considerations actually applicable to magical beings.
