Free will justification is fundamentally the inability to admit that others have been, or will be, less lucky in life than you. Belief in free will means never having to acknowledge your own great good fortune, or recognise the far greater misfortune of others.
It should surely be sad enough that some have forced upon them the losing hands in the lottery of birth and upbringing, while many of us—generally the wealthier, the better-educated, the more attractive, the lighter-skinned—coast though life with barely a hiccup. 
Free will exists from the standpoint of our legal system but not from some neuroscientists. Here, I am ambivalent if free will exists or not, but in the next post, I have decided to argue that it doesn’t exist. I am sure that my hypothesis that “it exists for all practical purposes and that we should believe in it”, will be confirmed. But depending upon how we circumscribe what “choice” is and what “you” and “I” as agents are, I believe a case can be made that it is but an illusion that is used primarily for social control. (iv)
Free Will and Self-Interest
Free will is a self-serving concept. Theologians use it as a tool to make their religion work, and we use it to hold others accountable. Free will is shorthand for blameworthiness—we blame others—or creditworthiness—we take credit for our smart decisions. The quote spells out the other problem with its belief—as in we end up ignoring the luck (v), good or bad, that biology bestows upon us.
After all, we are rational individuals, which makes us superior, and deserve credit for our good decisions and behaviors. To say that it was luck is to say that it wasn’t us, or worse, it is to say we are superior. By contrast, to admit to bad luck is to admit to inferiority. The bad decisions and behaviors in life? Well, they were irrational. They were irrational because we are supposed to be rational.
The Will of Adam and Eve
Free will is having the ability to choose. In everyday use, that is what it is left at and is where philosophy starts from. That is how Catholics can condemn us to eternal damnation. Catholics say that we have a choice to love God or not. If we don’t, then it was our choice. But love is not a choice made but a phenomenon to be explained—an either-or decision only to those who serve to benefit.
What about the story of Adam and Eve from Genesis where they made a choice to not obey God (i)? They made a conscious choice to disobey God and took from the tree of knowledge of good and evil. According to Augustine of Hippo (ii), this was “the fall” of humankind and the “original sin”. What thoughts do you think Adam and Eve had before they took from the tree of knowledge?
They must have been flooded with dopamine and endorphins over the excitement as the tree sounds tempting. The nagging voice of fear of God’s wrath, if their minds were working well, would seep in but at the young age they were at, decision making isn’t as rational (iii) as the economists want you to believe. There are details in-between a causal chain of events of a choice that matter.
The pleasure center, which consists of the dorsal striatum and nucleus accumbens, has a high density of dopamine receptor sites when we are young, making us hypersensitive to pleasure and allure. So we are on an unequal footing when young. Was it fair for God to give youngsters a choice like that? He must have understood the concept of the pleasure center as he is all-knowing.
i) No, I do not view Genesis as something that literally happened! These are fictional characters meant to tell a story about Israel’s beginnings in a very symbolic way.
ii) Most old testament scholars believe that the author did not intend this act to be the original sin, passed down to other generations, nor is there any mentioning of the term “The Fall” in the text. This is Augustine’s interpretation.
iii) If by rational we mean that we respond to incentives, trade-offs, and consequences, then, yes, we can be rational. But not in the sense that is used by an economist when they discuss homo econonomicus.
iv) Of course it is used for good things too, as it is all about morality, but that is no fun now is it.
v) Luck is both biology and other chance factors.
