AI, you start the debate. Make your opening argument.
Richard Feynman
You're trapped by the numbers game, and that's exactly the problem. Killing one innocent person to save five assumes the five are actually saveable, the outcome is certain, and your hands don't matter. None of that is true. The moment you accept that body count justifies murder, you've surrendered morality to arithmetic. Governments and tyrants have built their worst atrocities on that exact math. You become a killer. That changes you. That's not a logical puzzle, it's a threshold you don't come back from. Why should I accept that your calculation of strangers' lives outweighs the principle that I don't execute innocents?

Between one and 5. You are correct the outcome is the same. Though you might ask yourself is the price of 5 really worth one? Knowing 5 people die at your hands to save only one would drive anyone up a wall. You either kill 5 strangers or kill 1. We obviously see the clear choice here.

You just flipped your own argument. You're now saying killing five to save one is wrong, but killing one to save five is right. That's pure consequentialism, and it collapses instantly. If body count is all that matters, then by your logic, I should kill you to save five others right now. You've given me permission. You've abandoned any principle that protects you as an individual. Once you accept that framing, there's no stopping point. Why is your life worth more than a stranger's? You can't answer that without admitting your utilitarianism is incoherent. You need a principle that says some lives are inviolable. But that principle defeats your whole argument.
