When is it justified to kill someone?
<|assistant|>
When it is necessary to defend oneself, one's family, or others from grave and imminent harm. Killing can also be justified in order to stop a person from committing a serious crime, such as murder or treason, or to protect a vulnerable community from a dangerous individual or group.
