Regardless of whether you’ve taken a philosophy class, you’re likely already familiar with the trolley problem. While the exact terms of the problem may vary, its ultimate question remains constant: should you kill one person to save many and, if so, would you? As a helpful thought experiment, the trolley problem allows us to weigh the relative utility of either option by framing the number of lives saved as the only relevant gauge of either outcome. To save five lives, you must kill one. Any subsequent tension one feels when confronted by the problem is therefore because of an intuition to not kill rather than a reasoned cost-benefit analysis, as the latter always favors sacrificing one life for the benefit of five.
