Why Evil Breaks So Many Ideas About God

The problem of evil is one of those ideas that sounds tidy in a philosophy syllabus and absolutely brutal in real life.

It asks whether extreme suffering makes belief in an all-powerful, all-good God hard to defend, or maybe impossible.

And that question has been around forever because, frankly, it won’t go away. If God is omnipotent, God could stop horrors. If God is perfectly good, God would want to. So why are children crushed in earthquakes, why do people die slowly from disease, and why does cruelty keep getting so much room to breathe?

That’s the core of the problem of evil, and it’s bigger than a late-night dorm-room debate. In philosophy, theology, and ordinary moral life, the issue keeps returning because suffering keeps returning. The terms change. The examples don’t.

The Stanford Encyclopedia of Philosophy, in an entry first published on September 16, 2002 and substantively revised on March 3, 2015, puts the central issue with unusual clarity: evil raises the question of whether the world contains “undesirable states of affairs” serious enough to make belief in God unreasonable. That phrase, “undesirable states of affairs,” sounds bloodless. But it’s trying to cover everything from genocide to childhood cancer to animals suffering in the wild for no apparent reason.

So, yes, this is philosophy. But it’s also moral common sense refusing to shut up.

Why this argument hits people so hard

Some arguments against God feel technical. This one doesn’t.

The reason the problem of evil has such staying power is that it collides with basic human moral intuition. If a person had the power to stop a torture, a famine, or a child’s death and simply chose not to, we would call that monstrous. We would not shrug and say there must be a mysterious higher plan. We’d say that person failed in the most basic duty imaginable.

And that’s where the moral criticism of divine inaction gets sharp. The challenge isn’t just that suffering exists. It’s that suffering exists on a scale and with a pointlessness that seems wildly out of proportion to any lesson it might teach. A scraped knee can teach caution. A plague ripping through a village teaches what, exactly?

Philosophers usually split the issue into two broad versions. There’s the older, tougher deductive version, which tries to show God and evil are logically incompatible. Then there’s the evidential version, which says maybe they’re not flatly incompatible, but the amount and character of suffering in the world count as strong evidence against the traditional God of classical theism.

The SEP entry literally maps this debate across eight main sections. Eight. And section 3 alone breaks inductive arguments into five subtypes, including direct, indirect, and “Bayesian-Style Probabilistic Versions of the Evidential Argument from Evil.” Which is a very academic way of saying philosophers have spent a lot of time formalizing what ordinary people already feel in their gut: this world looks like a strange creation if it was made by a loving, unlimited being.

The classic religious answers, and where they wobble

Religious thinkers haven’t ignored this. They’ve built entire systems around it.

The SEP distinguishes three kinds of replies to the argument from evil: “attempted total refutations,” “defenses,” and “theodicies.” That distinction matters. A defense usually tries to show that God could have morally sufficient reasons for allowing evil, even if we don’t know them. A theodicy goes further and tries to say what those reasons actually are.

The most famous answer is free will. The basic thought is that a world with genuine moral freedom is better than one full of programmed puppets, and real freedom includes the possibility of terrible choices. Alvin Plantinga’s free will defense became hugely influential because it aimed to show that God and evil are not logically incompatible.

Fair enough, up to a point. Free will does explain some human cruelty. It helps explain murder, betrayal, war crimes, abuse.

But it does not explain why a child gets bone cancer. It does not explain parasites that blind people. It does not explain earthquakes, floods, tsunamis, or the long history of non-human animal suffering that existed long before humans were around making bad choices. The problem of evil has expanded far beyond “why do bad people do bad things?” It includes natural evil, random agony, and suffering built into biological life itself.

Then there’s soul-making, associated most often with John Hick. This says hardship can build courage, compassion, endurance, and moral depth. And sure, some suffering does that. People do become braver, kinder, and wiser through pain.

But some suffering just destroys people.

This is where the theory starts to look thin. There’s a vast moral gap between “difficulty can shape character” and “therefore Auschwitz, famine, torture, and infants dying in hospitals are part of a loving plan.” That leap is enormous. I’d go further: for a lot of people, it feels obscene.

Another response is the need for stable natural laws. A regular world, the argument goes, requires consistent physical processes. Gravity can’t only work when it’s convenient. Fire can’t only burn villains. That’s one reason a law-governed universe will contain accidents and disasters.

And yes, that’s more serious than the bumper-sticker version of theodicy. But it still leaves the scale problem. Why these laws, this biology, this amount of collateral damage? Why a system where conscious creatures are shredded by disease and disaster as the price of order?

Then there’s the oldest fallback of all: divine mystery. God’s reasons exceed human understanding.

Sometimes that’s intellectually honest. Sometimes it’s a dodge.

Where secular critics push hardest

Secular criticism usually lands on one point: many evils look gratuitous.

That word matters. A gratuitous evil is suffering that appears to serve no necessary greater good, no freedom-preserving purpose, no soul-making role, no intelligible function at all. A child dying in terror and confusion. An animal burning alive in a wildfire. A massacre that leaves no moral uplift behind, only grief and trauma spreading outward for decades.

If even some of those cases are truly pointless, the traditional picture of God starts to crack.

And no, critics aren’t saying every sad event disproves God. The stronger claim is cumulative. The sheer volume, distribution, and intensity of suffering make the God hypothesis look less plausible than believers often admit. That’s why evidential arguments have become so important. They don’t need a perfect contradiction. They just need the world to look more like what you’d expect without an all-good, all-powerful overseer.

Would we accept from a human ruler the excuses we accept from God?

That question is devastating because it exposes the moral asymmetry. If a government had the power to stop mass death and chose not to, we’d condemn it. If a parent stood by while a child suffered horribly for the sake of “character formation,” we’d call child abuse. But once the subject is divine inaction, people often switch ethical standards midstream.

That switch is doing a lot of work.

Why this isn’t just an academic fight

One reason this debate keeps escaping the classroom is that people run into it at funerals, in hospitals, and after disasters.

Crash Course Philosophy’s episode on the topic, “The Problem of Evil” (#13), has pulled 5.8 million views over 9 years, and the research snippet lists the channel at 17 million subscribers. Those numbers are wild for a philosophy problem that, on paper, sounds like something only grad students would argue about. But of course people click it. They’re not only looking for logic. They’re looking for a way to think when the usual religious lines stop working.

And lived experience changes the tone of the discussion. In abstract form, theodicies can seem elegant. In the presence of atrocity, they can sound unbearably polished. That doesn’t automatically make them false, but it does raise the stakes. If your explanation of suffering gets colder and cleaner as the suffering gets worse, something has gone wrong.

The problem also lands differently depending on what kind of God someone believes in. A distant deistic creator faces one kind of challenge. A personal God who loves each person, answers prayers, and could intervene at any moment faces a much sharper one. The more intimate and morally perfect the deity, the harder divine inaction is to square with reality.

What survives after the argument lands

For some believers, the problem of evil is a defeater. It breaks the whole structure.

For others, it doesn’t kill faith but changes it. God becomes less like a cosmic manager and more like a presence in suffering. The point shifts from explanation to solidarity, lament, protest, or hope. That move is emotionally powerful, though philosophically it can feel like changing the subject.

Still, that shift tells you something important. The argument from evil is so strong that even many religious responses no longer try to explain suffering in any neat way. They soften, retreat, or reroute. Instead of saying, “Here is why this horror had to happen,” they say, “We can’t know why, but God is with us in it.”

That may be spiritually meaningful. It is not the same thing as solving the problem.

And that’s where this debate is likely headed next. Less confidence in tidy theodicies, more pressure on the moral image of God itself, and more attention to victims rather than systems. The future of the argument probably won’t belong to the people with the slickest metaphysics. It’ll belong to whoever can look straight at real suffering and say something that doesn’t collapse under the weight of it.
