Is there a morally relevant difference between failing to prevent harm (omission) and contributing to it (commission)? Where does forwarding, joking or “reacting” in a chat fall?
The distinction between doing and allowing is one of the oldest and most contested in ethics. Most people feel that killing someone is worse than failing to save them, and that pushing someone into a river is worse than failing to pull them out. The law largely agrees: in England and Wales, as in most common-law systems, there is generally no duty to rescue a stranger, but there is always a duty not to harm one. A group chat that receives messages about a person in danger puts this distinction under pressure, because the actions available in a chat are neither clearly doings nor clearly allowings.
Why the distinction seems to matter
Several reasons are given for thinking that doing harm is worse than allowing it. One is about agency: when I harm you, I make myself the cause of your harm; when I fail to help, the cause is something else, and I merely fail to intervene. Another is about rights: you have a right that I not harm you, but it is less clear that you have a right that I help you, especially at cost to myself. A third is practical: a duty not to harm is easy to satisfy (just refrain), while a duty to help could become limitless, since there are always people somewhere who need help.
Philosophers such as Warren Quinn and Frances Kamm have defended versions of the distinction along these lines. Others, notably James Rachels, have attacked it, arguing that when all else is equal, letting someone die is no better than killing them. Rachels’s famous example compares a man who drowns his young cousin for an inheritance with a man who, intending the same, watches the child slip and drown without helping. It is hard to see that the second man is better.
Applying it to bystanders
Rachels’s point is important here. The doing and allowing distinction is most persuasive when the person who allows harm is distant, uninformed or would bear real costs by helping. It is least persuasive when the person allowing harm knows what is happening, could help at trivial cost, and has some relationship to those involved. A member of a group chat who receives messages indicating that someone is in danger, and who could call for help with a single phone call, is much closer to Rachels’s second man than to a distant stranger. His omission may not be equivalent to doing harm, but the gap is narrow.
Moreover, the no-duty-to-rescue rule is a rule of law, not morality. The reasons for it are largely about the limits of state coercion. Morally, almost everyone accepts that we have some duty to help when we can do so easily and the stakes are high.
Where chat actions fall
The more interesting question is how to classify the specific things people do in group chats. Simply reading a message and doing nothing is a pure omission. But chats invite small acts that are not omissions at all.
Forwarding is the clearest case of commission. To forward an image or message about someone in a vulnerable state is to distribute it, extending its audience and its harm. It is a positive act, and it can wrong the person depicted independently of anything else. If the image is intimate or degrading, forwarding it is a form of sexual exploitation, which campus codes and, in many places, criminal law now prohibit.
Joking is also a commission, though a subtler one. A joke in response to a report of harm does several things. It signals to others that the situation is not serious. It expresses approval or at least tolerance. And it shapes the norms of the group, making it harder for anyone else to respond with concern. A joke can therefore contribute to harm by encouraging those directly involved and discouraging those who might intervene.
Reacting with an emoji or a “like” sits between the two. It is a positive act, but a minimal one. Its meaning is often ambiguous: a laughing face might signal amusement, nervousness or disbelief. Still, reactions are public, they communicate attitudes, and they contribute to the sense of what the group finds acceptable. In a situation where silence would have been an omission, a reaction is a small act of participation.
Complicity without causation
One might object that forwarding, joking and reacting make no causal difference to what happens to the person at the centre. If the harm would have occurred anyway, how can these acts make someone responsible for it?
The answer, developed by Christopher Kutz, is that complicity does not require causal contribution. What matters is whether one participates in a shared project or expresses solidarity with wrongdoing. Someone who cheers on a crime, or joins in mocking its victim, aligns himself with it, even if his cheering changed nothing. He is answerable not for causing the harm but for taking part in it.
A graded picture
The result is a graded picture rather than a single line. At one end is the member who never saw the messages. Then the one who saw them and did nothing: an omission, and a serious one if he understood what was happening. Then the one who reacted: a minor commission expressing an attitude. Then the one who joked: a commission that shapes group norms. Then the one who forwarded: a commission that directly extends harm. And beyond all of these are those physically present and involved.
This gradation does not tell us what any particular person did. But it gives a vocabulary for distinguishing them, which is necessary for any fair assessment, and it shows why “I only reacted” or “I only forwarded it” is not the excuse it may seem.
