When Free Will Stops Explaining Evil
The free will defence has long been used to explain why a good God might permit evil. Yet once human behaviour is examined empirically, the amount of moral freedom this defence relies on begins to shrink. Trauma, biology, and circumstance place limits on agency that free will alone cannot plausibly carry.

The problem of evil is often framed as a tension between divine attributes and worldly suffering. If God is omnipotent, omniscient, and wholly good, why does evil exist? The most common answer has been free will. Evil is said to be the unavoidable cost of meaningful moral freedom. A world capable of genuine goodness must also permit wrongdoing.
This response has intuitive appeal. Moral responsibility seems to require alternatives. Praise and blame appear hollow if no other course of action was available. If God intervened whenever harm was imminent, human agency would seem undermined.
However, this defence weakens once we move from abstraction to how human behaviour actually functions.
Let's apply some empirical pressure on free will..
From psychology and sociology, harmful behaviour is not randomly distributed. Rates of violence, crime, and abuse correlate strongly with socioeconomic deprivation, childhood trauma, and generational instability. These relationships between environment and individuals are statistically robust and predictive across populations.
If morally harmful behaviour can be forecast based on conditions largely outside an individual's control, then the scope of free will involved in wrongdoing is significantly narrower than the free will defence assumes. Agency persists within constraints. Choice occurs within systems that bias outcomes well before conscious deliberation begins.
So lets explore neuroscience and that constrained agency..
Neuroscience applies further pressure here. Experimental work beginning with Libet and extended by later fMRI studies shows that neural activity predictive of a decision often occurs before conscious awareness of having decided. In many cases, the brain initiates action prior to conscious endorsement. So, with this new awareness, are you decisions even your own? or they simply responses from a complex cluster of physical matter (your body)?
A familiar example makes this concrete. I tell ask child to sit still and focus. He cannot. The child's mother explains, "He has ADHD." The behaviour reflects predictable neurological constraints.
No one seriously thinks the child could simply will himself into sustained attention. Free will, at most, appears as a thin supervisory layer operating within tight biological limits, many of which are statistically predictable. Once this is acknowledged, appeals to free will as a general explanation for wrongdoing look overstated. In other cases, constraint varies by degree.
But free will does not reach all suffering..
Even if some constrained form of free will survives, it cannot explain all suffering. Natural evils remain untouched. Childhood bone cancer. Parasitic insects that burrow into eyes and cause blindness. Earthquakes, fires, and disease that harm no moral agents and produce no discernible moral goods.
Stephen Fry highlights such cases precisely because they bypass human choice entirely. They are not consequences of moral failure. They are features of the natural order.
So perhaps suffering serves a greater good..
In principle, permitting harm can be morally justified if preventing it would cause a worse catastrophe. A standard analogy comes from World War II. After cracking the Enigma code, British intelligence sometimes allowed attacks to proceed, knowing that consistent interference would reveal the breach and cost the war. Local harms were permitted to prevent vastly greater global suffering.
This justification works because it involves genuine constraints. British command lacked omnipotence. There were real trade-offs and no alternative means available.
The analogy weakens when applied to God. An omnipotent being does not face intelligence limitations, secrecy constraints, or zero-sum trade-offs. God could prevent both the local harm and the global catastrophe simultaneously, unless omnipotence is meaningfully restricted.
Yet some suffering appears to serve no purpose..
This brings us to William Rowe's example of a fawn trapped in a forest fire, suffering for days before dying alone. No one witnesses it. No lesson is learned. No greater harm is prevented.
The case shows that some suffering appears gratuitous. If such suffering exists, then a wholly good, omnipotent God becomes less probable without becoming logically impossible. Appeals to unknown divine reasons remain available, but at the cost of draining claims about God's goodness of moral content.
Which raises questions about moral alignment..
At this point, an uncomfortable possibility emerges. Perhaps the problem begins with our assumption that God is morally aligned with human values. The world contains suffering, joy, beauty, and indifference in vast measure. If God exists and is an emotional being, perhaps God values the full spectrum and gives moral goodness no privileged position.
Yet this fares poorly. Emotions are unreliable and often distort judgement. A God who enjoys suffering would be morally monstrous. Classical theism avoids this by denying divine emotions, but once divine impassibility is accepted, appeals to God's care become increasingly abstract.
The problem deepens with divine silence. John Schellenberg argues that a perfectly loving God would ensure that all capable, willing persons could enter into relationship with God. The existence of non-resistant non-believers suggests otherwise.
So where does this leave the picture of God..
None of this logically disproves God. What it undermines is a specific picture of God, one whose moral governance is adequately explained by human freedom and inscrutable greater goods.
What remains are harder options. God exists but is morally alien. God exists but traditional theism is mistaken. Or God does not exist. The data alone does not force a single conclusion.
What it does force is honesty about how much explanatory weight free will can realistically carry, and whether moral meaning is something the world contains or something we impose upon it.
