What this dot point is asking
AQA wants you to apply the three normative theories (utilitarianism, Kantian deontology and Aristotelian virtue ethics) to the four set issues: stealing, simulated killing (in drama, film and video games), eating animals, and telling lies. You must explain what each theory says about each issue and use these applications to evaluate the theories.
Stealing
Simulated killing
Simulated killing covers killing within drama, film and video games, where no real person is harmed.
- Utilitarianism: judges it by consequences, such as enjoyment and catharsis weighed against any tendency to desensitise or encourage real violence; the evidence about effects is what matters.
- Kant: no real person is treated merely as a means, so it is not straightforwardly forbidden, though Kant's remarks on cruelty to animals suggest indulging in simulated cruelty may corrupt one's character and respect for humanity.
- Virtue ethics: focuses on what taking pleasure in simulated killing does to character: whether it cultivates or coarsens compassion and the virtues, which can vary with the person and the context.
Eating animals
- Utilitarianism: because sentient animals can suffer, their pain counts (Bentham: "can they suffer?"); Singer argues factory farming causes vast suffering that outweighs the pleasure of eating meat, so much meat-eating is wrong.
- Kant: animals are not rational ends in themselves, so we have no direct duties to them, only indirect duties (cruelty to animals tends to harden us towards people).
- Virtue ethics: asks whether eating animals, and how they are reared, expresses virtues such as compassion and temperance or vices such as cruelty and greed.
Telling lies
What the applications reveal
- Utilitarianism is flexible and sensitive to circumstances but can license intuitively wrong acts and depends on uncertain predictions.
- Kantian ethics gives firm, principled prohibitions but can seem rigid and indifferent to disastrous consequences.
- Virtue ethics captures the role of character and judgement but can be vague about what to do in a hard case.
Using the applications to evaluate
The exam reward is not just reciting verdicts but using the four issues as test cases that expose each theory's strengths and weaknesses. Stealing is a good probe of Kant: the firm prohibition looks attractive in ordinary cases but the hard case of stealing bread to feed a starving family suggests his absolutism is too rigid, whereas utilitarianism's flexibility here looks like a strength until you notice it could also license theft that merely happens to maximise utility. Lying probes the same fault line from the other side: most people share the intuition that a protective untruth to a murderer is permissible, which counts against Kant and for both utilitarianism and virtue ethics, yet utilitarianism's licence to lie whenever it pays threatens the trust that makes communication possible, which is precisely the point Kant's universalisation test was built to capture.
Eating animals sharpens the contrast over moral status. Utilitarianism extends the moral circle to all sentient beings and so gives a clear, principled critique of factory farming, while Kant's denial of direct duties to non-rational animals strikes many as a defect of his rationalism, and virtue ethics reframes the question around the agent's character (compassion, temperance) rather than the animal's status, which some find illuminating and others find evasive. Simulated killing tests whether a theory can handle a case with no direct victim: utilitarianism must appeal to contested empirical evidence about effects, Kant must reach for indirect duties, and virtue ethics is arguably best placed because its focus on what an activity does to character does not require a victim at all. Running these comparisons is what turns description into the evaluation the longer questions reward.
Exam-style practice questions
Practice questions written in the style of AQA exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
AQA 20185 marksExplain how a Kantian would assess telling a lie.Show worked answer →
A 5 mark "explain" on Paper 1 wants the application run through Kant's actual test, not just the verdict.
State the maxim ("I will lie to get what I want") and apply the Formula of Universal Law: universalised, lying generates a contradiction in conception, because if everyone lied when convenient the practice of asserting and being believed would collapse, so the maxim cannot be universalised. Add the Formula of Humanity: lying treats the hearer merely as a means, manipulating their rational agency by feeding them false information they would not consent to, so it fails to treat them as an end. Conclude that lying violates a perfect duty and is therefore always wrong, and note Kant's hard case (you must not lie even to the murderer at the door) as the application that shows how strict the verdict is.
AQA 20205 marksOutline a utilitarian argument against eating factory-farmed animals.Show worked answer →
Markers want the consequentialist reasoning, not just the conclusion.
Set it out: utilitarianism counts the happiness and suffering of all sentient beings impartially (Bentham, "the question is not, Can they reason? but, Can they suffer?"); sentient animals can suffer, so their pain has the same moral weight as comparable human pain; factory farming inflicts vast, intense and prolonged suffering on enormous numbers of animals; the pleasure humans gain from eating that meat is comparatively minor and replaceable by alternatives; so the suffering outweighs the benefit and the practice fails the greatest happiness test (Singer). A strong answer flags that this is a case-by-case verdict, so less intensive farming might come out differently.
AQA 202212 marksExplain how utilitarianism, Kantian ethics and virtue ethics each treat the issue of simulated killing.Show worked answer →
A 12 mark "explain" wants three accurate applications to the same case, with the reasoning of each theory made clear, no evaluation required.
Frame the issue: simulated killing in drama, film and video games, where no real person is harmed. Utilitarianism judges it by consequences, weighing enjoyment and catharsis against any empirically supported tendency to desensitise or encourage real violence, so the verdict tracks the evidence about effects. Kantian ethics finds no person treated merely as a means in the simulation itself, so it is not directly forbidden, but Kant's remarks on cruelty (his claim that cruelty to animals hardens us towards people) suggest indulging in simulated cruelty may corrupt one's character and so engage an indirect duty. Virtue ethics asks what taking pleasure in simulated killing does to character, whether it cultivates or coarsens compassion and the other virtues, a question whose answer depends on the person, the work and the spirit in which it is engaged. Top answers keep the three lines of reasoning distinct and tie each verdict to the theory's own criterion.
