Intent or outcome: what matters more?

Note: Café Philo is a way of meeting interesting, inquiring people who enjoy talking about life's big issues and conundrums in a convivial atmosphere, rather than a heavy-duty philosophy seminar. Read more about our approach here.
This question sits at the heart of two big moral approaches: consequentialism (focus on results) and deontology (focus on duties, rules, and intentions). We will explore why people divide on this and what each side finds compelling
Intention vs. outcome
One way of thinking about morality says what really counts is why you act: the principles you follow, the duties you respect, and the kind of will you express. Another way says what ultimately matters is what actually happens in the world — who ends up better or worse off.
This leads to familiar puzzles:
- If someone means well but causes harm, how should we judge them?
- If someone does something cold-blooded but helpful, is that morally good?
- Are some actions always off-limits, no matter the benefits?
- The role of luck: e.g., two drivers use their mobiles while driving: one has an accident and kills a pedestrian; the other arrives home without incident. Is the former more morally culpable than the latter? If so, why?
## Consequentialism (outcome-focused)
Consequentialists say the right action is the one that produces the best overall outcome for everyone affected.
Why people like it:
- It offers a single clear test: compare outcomes and pick the option with the best balance of good over bad (less suffering, more happiness, better well-being).
- It’s impartial: my well-being doesn’t matter more just because it’s mine. This gives us reasons to care about strangers, future generations, and even animals.
- It helps in hard cases: triage decisions, disaster planning, or situations where all options are bad. It gives a structured way to minimise harm.
Why people worry about it:
- It seems demanding: if you must always maximise the good, there’s little room for personal projects or special concern for friends and family.
- It can seem to justify injustice, like harming one person to help many.
- We’re bad at predicting outcomes, which makes morality feel unstable or too reliant on guesswork.
## Deontology (duty/intent-focused)
Deontologists think some actions are right or wrong because of the principles behind them — not just because of what happens afterward.
Why people like it:
- It protects strong rights: you must not kill, coerce, deceive, or use people merely as a tool.
- It emphasises respect for persons: morality is about how we treat others as agents with dignity.
- It avoids making blameworthiness depend on luck: two people with the same intentions shouldn’t be judged differently just because one got unlucky.
- Clear rules and duties fit everyday moral thinking and don’t require endless calculation.
Why people worry about it:
- It can feel rigid: “never lie” sounds strange when a lie might save a life.
- Duties can conflict, and resolving conflicts often sneaks in consequentialist reasoning anyway.
- It sometimes seems to ignore outcomes too much, especially when consequences are huge.
## Thought experiment: the trolley problem
In this classic and familiar case, a runaway trolley will plough into and kill five people working; you can divert it to a siding, but unfortunately this will result in one person’s death. Most people say they would pull the lever, suggesting they hold a consequentialist moral postion. Do you agree?
Another thought experiment: organ harvesting
A healthy person comes in for a routine check-up. Five patients in the clinic need different organs and will die soon. A surgeon could secretly kill the healthy visitor and save all five. The numbers are the same as in the trolley problem (kill one to save five). Consequentialists might therefore say one death instead of five looks like the better outcome; while the deontological view would be that intentionally killing an innocent person for others’ benefit is simply wrong — it violates their rights and treats them as a means.
Questions to ponder:
- Would anything justify the surgeon killing the healthy person?
- Why is it different from pulling the lever in the trolley case?
- Do your intuitions change if the numbers change? Say 20 people? 100
How does this example differ, if at all, from the following situations:
- triage in an over-whelmed field hospital, where the older and most seriously injured are left untreated in favour of younger and more easily treatable?
- a wartime decision to take action that could save thousands but will likely kill at least some civilians?
- the dropping of the atom bomb on Hiroshima/Nagasaki, leading to the earlier end of World War II?
