When is trickery justified?

Trickery may be justified in situations where it serves a greater good, such as protecting someone from harm or preventing a larger injustice. For instance, deceiving an oppressor to safeguard a vulnerable individual can be seen as morally acceptable. However, ethical considerations must weigh the potential consequences and the intent behind the trickery, ensuring it aligns with principles of fairness and justice. Ultimately, the justification often hinges on the context and the impact on those involved.
