Graphic details of Charlie Kirk’s death have been almost unavoidable on social media in recent days. Similarly, shocking footage of an unprovoked knife attack on 23-year-old Iryna Zarutska on a train in Charlotte, North Carolina last month, has been widely circulated. Add to that the videos coming out of Gaza, Ukraine or Sudan. Seeing such images changes us. We can’t unsee them. They shock us, anger us, frighten us, stir our empathy, shift our moral compass.

Do we have a moral duty to watch real-life violence order to gain a deeper understanding of a situation? For example, would George Floyd’s death have had the same imaginative power if it hadn’t been filmed? Or is the truth-seeking instinct sometimes misplaced, driven by morbid curiosity and voyeurism, risking desensitisation, compassion fatigue or, conversely, chronic anxiety and stress? Do such stark images give us a moral anchor in a storm of spin and misinformation, or are we in danger of missing important context and using the intimately personal moment of a human death as a weapon in a heated political arena? With social media moderators being cut and TV news channels under pressure to beat the competition for pictures, what does the choice to publish and consume ever more extreme content say about us, and the dignity of those whose lives and deaths we are a witness to?

When should we choose to see or not to see – to know or not to know?
